Purpose
Enters BGP configuration mode, allowing you to configure the
BGP routing process.
Use the show bgp command in EXEC mode to obtain the
autonomous-system-number for the current router.
Sets the BFD minimum interval. Range is 15-30000 milliseconds.
Sets the BFD multiplier.
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 5.
In the example in Step 5, 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.
