9.3 BGP peer

BGP Command: neighbor peer remote-as as-number {}

Creates a new neighbor whose remote-as is as-number. peer can be an IPv4 address or an IPv6 address.

router bgp 1 neighbor 10.0.0.1 remote-as 2

In this case my router, in AS-1, is trying to peer with AS-2 at 10.0.0.1.

This command must be the first command used when configuring a neighbor. If the remote-as is not specified, bgpd will complain like this:

can't find neighbor 10.0.0.1
