[nsp] question on BGP

[Lucas Iglesias]

Benjie,

It's absolutely possible, we have the same issue and it has been working
fine for the last 3 years. The only issue is, as you 've said, that
advertisements form one office won't be seen on the other one. You don't
even need ibgp between them (it's better if you have it) but shouldn't be a
requirement. Of course, the prefixes advertised by one have to be added
manually on the other one (or you must have a default route so they can have
connectivity between them).

Hope this helps.
Luckas.

Asunto: [nsp] question on BGP


Hi list,

Is it possible to have two offices connected to the
same service provider to share the same AS but still
maintain connectivity.


office 1 [AS1000] <-->service provider <--> office 2
[AS1000]

Office 1 and 2 have no direct connectivity.
Both offices need to use BGP since they will be
multihomed to different providers.
I know office 1 cannot accept BGP advertisement from
office 2 since it  its own AS.
Is there a way to make this work without using GRE
tunnels between the two offices? 
My only idea is to get a different AS for office 2.
Thanks.
