BGP different AS same router

Sun Oct 22, 2017 12:58 am

Hello everyone,
Can't find a solution how to configure.

I have two AS with different pools of real ip. Can't combine them in RIPE because of "corporate issies".

Each of this AS are stub, so I have the only one uplink, that sends me default route for each AS. Neighbor is same too, but p2p adresses to each router are different.

In that moment it is configured on separarate routers mikrotik and quagga. One AS for one router. Could it be solved with one mikrotik, that announces 2 AS to a "big brother".

Have you tried 2 BGP Instances (different local AS) and 2 separate Peers?
If you are running 2 x default routes, maybe a local VRF-Lite might help if you want to separate the routing tables.

Solved. It's a good idea not to forget about routing filters :) (to separate announces from each AS)
