Enabling BGP PIC Edge: IOS-XR • Two BGP-PIC Edge Flavours: BGP PIC Edge Multipath and Unipath • Multipath: Re-routing router load-balances across multiple next-hops, backup next-hops are actively taking traffic, are active in the routing/forwarding plane, commonly found in active/active redundancy scenarios.. IOS-XR also has similar FIB structure, starting from VRF prefix -> label -> BGP protocol next hop -> IGP next hop -> Port channel -> OIF, give or take one for two levels depending on the feature(s) one's using. That's why the more features you turn on, the more hardware is needed, the more heat is produced, the bigger the power bill gets etc etc. protect a primary pseudowire that fails. G.8032: G.8032 is a feature that provides the sub-50-ms protection for Ethernet traffic in a ring topology. The implementation on the Cisco ASR 9000 Series is compliant with version 2 of the ITU-T standard. pseudowires together to form a cross-connect relationship. Static Route Configuration Examples in Cisco (IOS-XR) for BGP aggregated prefix advertisements In order to advertise the aggregated routes (and default routes) via BGP, it should exists in the routing table, that's the #1 rule. If these summarized routes (/16) are not existing and only smaller subnets are learned via the IGP(e.g. OSPF,IS-IS), then configure. This is the post demonstrate interesting features I came across in the book <BGP>. Here is my original blog BGP soft-reconfiguration inbound By default, when soft-reconfiguration inbound not enabled and run clear ip bgp x.x.x.x, the BGP peer will close BGP connection: *Jun 15 19:03:23.917: %BGP-3-NOTIFICATION: received from neighbor 10.1.0.2 6. There are three possible points (Cisco IOS XR calls it attach point), where you can apply routing policy: In case of BGP configuration mode these policies will be used for prefixes send/receiving to/from all BGP neighbors. In case of group sub mode in BGP these policies will be used for prefixes send/receiving to/from BGP neighbors within this.

This chapter also provides details on Routing Policy Language as a vehicle. Local preference is the second BGP attribute and is used to choose the exit path for an autonomous system. The BGP preference has to be set inbound on routes being received to influence the outbound routing behaviour. A higher local preference is preferred and the default is 100.

In case of replace, if there is a diff between the existing configuration and the input configuration, the existing configuration will be replaced by the input configuration for every option that has the diff. In case of override, all the existing BGP configuration will be removed from the device and replaced with the input configuration. BGP SoO is a tag that is appended on BGP updates to allow a peer to mark a particular peer as belonging to a particular site. In certain MPLS L3 VPN configurations, the BGP AS-Path may not provide the granularity needed prevent a loop in the control-plane. With this in mind, BGP SoO is designed to fill this gap and prevent a routing loop that. How to Configure BGP in IOS-XR | Step-by-Step. Steps in Upgrading Cisco IOS-XR code.
