[nsp] Multi-VRF BGP: Does it support unique BGP AS number per VRF?

[Scott Morris]

If you wanted to do that in order to peer with each customer separately
(first, I'd ask why!), but then I'd suggest using the 'local-as' feature
to override your default AS when advertising to each particular
neighbor.

There are some caveats to it, like it must be on a true ebgp
connection...  But it can be done.  Check out:

Is it possible to put in unique BGP AS number under each customer VRF
config 
in BGP? It's like creating multiple virtual customer BGP routers with
each 
VRF having its own BGP AS number. Right now it seems like it can't be
done 
(I am using IOS 12.3.1a) and all VRFs inherit the same BGP AS number
that 
was defined under the global BGP process.

With Multi-VRF EIGRP (new in IOS 12.2.15T) I was able to enter unique
EIGRP 
process number in a per-VRF environment. I wish I can do the same for 
Multi-VRF BGP.

Thanks,

William Chu
