BGP Confederation Peers - Configuration ??

Jamie_90

Level 1

When configuring the

BGP confederation peers

in a network with multiple AS's. Do we specify all of the peers or only the connected ones?

For example, would R1's configuration look like this: 

router bgp 65002
  bgp confederation identifier 1234
  bgp confederation peers 65001 65003 65004 65005 65006
!

Or like this: 

router bgp 65002
  bgp confederation identifier 1234
  bgp confederation peers 65001 65003 
!

Cisco documentation states the command purpose as "Specifies the autonomous systems that belong to the confederation." So I would assume all of them?

Any online examples only include two AS's within the confederation.

Hello @Jamie_90,

in a BGP confederation setup, you would specify all of the autonomous systems that belong to the confederation.

This includes both directly connected peers and other ASes within the confederation. The

bgp confederation peers

command is used to list all the AS numbers that are part of the same confederation.
