BGP: Only possible to set neigbor once

[Alexander Zubkov]

Hi,

>From my understanding, there can be only one neighbor here, but you can set
different parts of it with multiple directives, i.e.:

neighbor 10.0.1.1;
neighbor as 65000;

But two different IPs would be two neighbors and you must have two separate
bgp protocols for that. Or a dynamic protocol that spawns specific
protocols.

Regards,
Alexander
