BGP removing my ASn?

[grzesjan]

Hello,

I have two separate subnets, with separate internet bgp feeds, but they use the same ASn. Something like that:

AS12345 – INTERNET – INTERNET – INTERNET – AS12345

Of course there are different IP subnets announced. Both bgp routers are Mikrotiks 2.9.29-31.

Am I missing something? Is Mikrotik’s bgp removing it’s own AS number if it is received from other peer? Both bgp routers don’t see prefixes announced by another one. All the rest of internet sees all prefixes from both routers.

Please advice me something, thanks in advance.

Regards,

Gregor,

this is normal … ebgp will remove your own AS numbers since it figures you can get there other ways (part of the same autonomous system). You can run ibgp between them to exchange your own routes if you need, or just let it use the default gateway if that works for you.

Is it normal for BGP or for Mikrotik? I cannot check it but I don’t remember similar problems with quagga/cisco.

you can allways google for BGP RFC and nail MT if they make something diferently, atleast you can ask them to stick with RFC. as far as i know they are sticking with RFC
