Hub & Spoke an example of VRF-Lite
 
09:53
VRF Lite means VRF without the need to run MPLS in the network. VRF Lite allows the network administrator to create multiple routing instances on the same routing device within the enterprise. VRF Lite can be useful when you need to isolate traffic between two networks sharing the same routing platform or if you have multiple networks with overlapping addresses sharing the same physical network. Multiple instances of routing protocols can be used for different VRFs on the same device to exchange routes dynamically with a direct connected device.

When BGP tries to install the bestpath prefix into Routing Information Base (RIB) (for example, the IP Routing table), RIB might reject the BGP route due to any of these reasons: Route with better administrative distance already present in IGP. For example, if a static route already exists in IP Routing table. Memory failure. The number of routes in VPN routing/forwarding (VRF) exceeds the route-limit configured under the VRF instance. In such cases, the prefixes that are rejected for these reasons are identified by r RIB Failure in the show ip bgp command output and are advertised to the peers.

These route-propagation rules effectively require that all iBGP peers inside an AS are interconnected in a full mesh. How routes are propagated can be controlled in detail via the route-maps mechanism. This mechanism consists of a set of rules. Each rule describes, for routes matching some given criteria, what action should be taken. The action could be to drop the route, or it could be to modify some attributes of the route before inserting it in the routing table.

MBGP using eNSP
 
25:06
Multiprotocol Extensions for BGP (MBGP), sometimes referred to as Multiprotocol BGP or Multicast BGP and defined in IETF RFC 4760, is an extension to Border Gateway Protocol (BGP) that allows different types of addresses (known as address families) to be distributed in parallel. Whereas standard BGP supports only IPv4 unicast addresses, Multiprotocol BGP supports IPv4 and IPv6 addresses and it supports unicast and multicast variants of each. Multiprotocol BGP allows information about the topology of IP multicast-capable routers to be exchanged separately from the topology of normal IPv4 unicast routers. Thus, it allows a multicast routing topology different from the unicast routing topology. Although MBGP enables the exchange of inter-domain multicast routing information, other protocols such as the Protocol Independent Multicast family are needed to build trees and forward multicast traffic. Multiprotocol BGP is also widely deployed in case of MPLS L3 VPN, to exchange VPN labels learned for the routes from the customer sites over the MPLS network, in order to distinguish between different customer sites when the traffic from the other customer sites comes to the Provider Edge router (PE router) for routing.

IPSec Site-to-Site VPNs w/Static Virtual Tunnel Interfaces (SVTI): IKEv1 & IKEv2
 
02:36:29
The following video tutorial takes a deep dive into Static Virtual Tunnel Interface (SVTI) interfaces along with both IKEv1 and IKEv2. We explore all the similarities and differences between the configuration and operation of SVTIs with IKEv1 and IKEv2. The IKEv1 scenario connects two offices together over the Internet and the IKEv2 scenario connects up two offices over an MPLS L3 VPN architecture. Thanks to some typos we also get to troubleshoot what happens when you use a route-map with the wrong name, what happens when a route is learned via eBGP and you want it to be learned via EIGRP (AD concerns!), and when you enter in IP addresses wrong (good troubleshooting)! In each scenario the configuration for either EIGRP or OSPF is done so you can see how to run either routing protocol over your SVTI. The next video will show the same thing, but with crypto-maps! Enjoy!

These settings are global for an address family. For some routes this may not be appropriate. For example, static routes may need to be redistributed with a next hop of self, but connected routes and routes learned via Interior Border Gateway Protocol (IBGP) or Exterior Border Gateway Protocol (EBGP) may continue to be redistributed with an unchanged next hop. The BGP route map next hop self functionality modifies the existing route map infrastructure to configure a new ip next-hop self setting, which overrides the bgp next-hop unchanged and bgp next-hop unchanged allpaths settings. The ip next-hop self setting is applicable only to VPNv4 and VPNv6 address families. Routes distributed by protocols other than BGP are not affected. You configure a new bgp route-map priority setting to inform BGP that the route map will take priority over the settings for bgp next-hop unchanged and bgp next-hop unchanged allpath. The bgp route-map priority setting only impacts BGP. The bgp route-map priority setting has no impact unless you configure the bgp next-hop unchanged or bgp next-hop unchanged allpaths settings. Route Filtering and Manipulation Route filtering is a method for selectively identifying routes that are advertised or received from neighbor routers. Route filtering may be used to manipulate traffic flows, reduce memory utilization, or to improve security. For example, it is common for ISPs to deploy route filters on BGP peerings to customers. Ensuring that only the customer routes are allowed over the peering link prevents the customer from accidentally becoming a transit AS on the Internet. Filtering of routes within BGP is accomplished with filter-lists, prefix-lists, or route-maps on IOS and NX-OS devices. default-information originate (OSPF) To generate a default external route into an Open Shortest Path First (OSPF) routing domain, use the default-information originate command. To disable this feature, use the no form of this command. default-information originate [ always ] [ route-map map-name ] no default-information originate [ always ] [ route-map map-name ] Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet.

You will see that choosing the type of identity to send and match becomes very important as the certificate does not get exchanged until later in Phase 1 negotiation. Using aggressive mode allows the device identity contained in the certificate to be revealed sooner but at a risk of identity exposure. Aggressive mode will also be reviewed in this video.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Multiprotocol Extensions for BGP (MBGP), sometimes referred to as Multiprotocol BGP or Multicast BGP and defined in IETF RFC 4760, is an extension to Border Gateway Protocol (BGP) that allows different types of addresses (known as address families) to be distributed in parallel. Whereas standard BGP supports only IPv4 unicast addresses, Multiprotocol BGP supports IPv4 and IPv6 addresses and it supports unicast and multicast variants of each. Multiprotocol BGP allows information about the topology of IP multicast-capable routers to be exchanged separately from the topology of normal IPv4 unicast routers. Thus, it allows a multicast routing topology different from the unicast routing topology. Although MBGP enables the exchange of inter-domain multicast routing information, other protocols such as the Protocol Independent Multicast family are needed to build trees and forward multicast traffic. As an enhancement of BGP-4, MP-BGP provides routing information for various protocols, such as IPv6 (BGP4+) and multicast: MP-BGP maintains unicast and multicast routing information, and stores both types in different routing tables to ensure their separation. MP-BGP supports unicast and multicast, and constructs different network topologies for each. MP-BGP can maintain unicast and multicast routes based on routing policies. The unicast routing policies and configurations supported by BGP-4 can mostly be applied to multicast. Multiprotocol BGP is also widely deployed in case of MPLS L3 VPN, to exchange VPN labels learned for the routes from the customer sites over the MPLS network, in order to distinguish between different customer sites when the traffic from the other customer sites comes to the Provider Edge router (PE router) for routing.

IPsec Overview: A secure network starts with a strong security policy that defines the freedom of access to information and dictates the deployment of security in the network. Cisco Systems offers many technology solutions for building a custom security solution for Internet, extranet, intranet, and remote access networks. These scalable solutions seamlessly interoperate to deploy enterprise-wide network security. Cisco System's IPsec delivers a key technology component for providing a total security solution. Cisco's IPsec offering provides privacy, integrity, and authenticity for transmitting sensitive information over the Internet. IPsec provides secure tunnels between two peers, such as two routers. You define which packets are considered sensitive and should be sent through these secure tunnels, and you define the parameters which should be used to protect these sensitive packets, by specifying characteristics of these tunnels. Then, when the IPsec peer sees such a sensitive packet, it sets up the appropriate secure tunnel and sends the packet through the tunnel to the remote peer. More accurately, these tunnels are sets of security associations (SAs) that are established between two IPsec peers. The security associations define which protocols and algorithms should be applied to sensitive packets, and also specify the keying material to be used by the two peers. Security associations are unidirectional and are established per security protocol (AH or ESP). With IPsec you define what traffic should be protected between two IPsec peers by configuring access lists and applying these access lists to interfaces by way of crypto map sets. Therefore, traffic can be selected based on source and destination address, and optionally Layer 4 protocol, and port. The access lists used for IPsec only determine which traffic should be protected by IPsec, not which traffic should be blocked or permitted through the interface. Separate access lists define blocking and permitting at the interface. A crypto map set can contain multiple entries, each with a different access list. The crypto map entries are searched in order—the router attempts to match the packet to the access list specified in that entry. It is good practice to place the most important crypto map entries at the top of the list. When a packet matches a permit entry in a particular access list, and the corresponding crypto map entry is tagged as cisco, then CET is triggered, and connections are established if necessary. If the crypto map entry is tagged as ipsec-isakmp, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, IPsec uses the Internet Key Exchange protocol (IKE) to negotiate with the remote peer to set up the necessary IPsec security associations on behalf of the data flow. The negotiation uses information specified in the crypto map entry as well as the data flow information from the specific access list entry. If the crypto map entry is tagged as ipsec-manual, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, the traffic is dropped. In this case, the security associations are installed via the configuration, without the intervention of IKE. If the security associations did not exist, IPsec did not have all of the necessary pieces configured. Once established, the set of security associations (outbound, to the peer) is then applied to the triggering packet as well as to subsequent applicable packets as those packets exit the router. Applicable packets are packets that match the same access list criteria that the original packet matched. For example, all applicable packets could be encrypted before being forwarded to the remote peer. The corresponding inbound security associations are used when processing the incoming traffic from that peer. If IKE is used to establish the security associations, the security associations will have lifetimes set so that they periodically expire and require renegotiation, thus providing an additional level of security. Multiple IPsec tunnels can exist between two peers to secure different data streams, with each tunnel using a separate set of security associations. For example, some data streams might be just authenticated while other data streams must both be encrypted and authenticated.

Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet.[1] The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol. The Border Gateway Protocol makes routing decisions based on paths, network policies, or rule-sets configured by a network administrator and is involved in making core routing decisions.

The BGP Visibility Scanner
 
24:49
Speakers: Andra Lutu, Institute IMDEA Networks - UC3M Andra Lutu is a third-year PhD student at Institute IMDEA Networks and University Carlos III of Madrid, Spain. Since 2009, she has been working alongside her advisor, Marcelo Bagnulo, in topics closely related to interdomain routing. Her research interests orbit around BGP and its intricacies, with a focus on measurements and game theory models. Abstract: By tweaking the BGP configurations, ASes are able to express their interdomain strategies and deploy the above-mentioned policies. However, due to the complex interactions between networks, at times only defining a routing policy does not also guarantee its effectiveness in the Internet. For examples, sometimes, BGP routes end up being announced to entities to which the routing policies specifically state that they should not be. And it may also happen that, by default, all the routes are propagated to all BGP neighbors, once they have been accepted, disregarding of the origin’s strategies. Consequently, the network operators need to complement the view of the routing system from inside their network with multiple external views, in order to understand how their policies interact with the operations of the rest of entities in the interdomain and if the implemented policies are producing the intended or expected result. - See more at: https://www.nanog.org/meetings/nanog57/agenda

Anatomy of a Leak: AS9121 (or, "How We Learned To Start Worrying and Hate Maximum Prefix Limits")
 
33:55
Speakers: Alin C. Popescu, Renesys Corporation. Brian J. Premore, Renesys Corporation. Todd Underwood, Renesys Corporation. Large-scale leaks have caused routing problems on the Internet in the past. On Dec 24, 2004, AS9121 announced over 100K routes to their peers, resulting in widely propagated invalid routes. Many large networks carried over 25K bad paths during the event, and some as many as 100K. Using BGP updates from approximately 80 peering sessions during the event, we analyze the event including the worst-hit networks, and the networks that spread the most bad paths. We find that network distance from AS9121 and maximum prefix settings on BGP sessions were not enough to prevent networks from carrying the bad prefixes. Finally, we review operational lessons learned (from feedback from involved networks) and make suggestions on future mitigation strategies. See more at: https://www.nanog.org/meetings/nanog34/agenda

Video page http://www.labminutes.com/sp0005_mpls_targeted_ldp more MPLS videos at http://www.labminutes.com/video/sp/mpls The video shows a way of reducing convergence time of LDP on Cisco router with targeted LDP. You will see how targeted LDP is able to maintain LDP session to a neighbor router even after a link to that router has gone down so they do not need to go through session establishment and label exchange after link recovery, and, hence, improve convergence time. While targeted LDP requires specific configuration between two LDP peers, session protection allows you to create targeted LDP to all neighbors with essentially a single command and this will also be covered in this video.
