[nsp] question on BGP

[Benjie Ko]

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.
