Implementing BFD

Enabling BFD on a BGP Neighbor

BFD can be enabled per neighbor, or per interface. This task describes how to enable BFD for BGP on a
neighbor router.

Routing Configuration Guide for Cisco NCS 5500 Series Routers, IOS XR Release 6.3.x
Enabling BFD on a BGP Neighbor
Purpose
Enters BGP configuration mode, allowing you to configure
the BGP routing process.
Places the router in neighbor configuration mode for BGP
routing and configures the neighbor IP address as a BGP
peer.
This example configures the IP address 172.168.40.24 as
a BGP peer.
Creates a neighbor and assigns it a remote autonomous
system.
This example configures the remote autonomous system to
be 2002.
Enables BFD between the local networking devices and the
neighbor whose IP address you configured to be a BGP
peer in Step 3.
In the example in Step 3, the IP address 172.168.40.24 was
set up as the BGP peer. In this example, BFD is enabled
between the local networking devices and the neighbor
172.168.40.24.
