Hi Peng:
I don't think I understand what your question was.
There are two commands associated with the BGP confederation:
1) bgp confederation identifier <AS#>
2) bgp confederation peers <sub-AS#1, sub-AS#2...sub-AS#n>
If I do BGP confederation, I divide my AS in to multiple sub-ASs. And each
sub-AS is treated like an individual system, and I configure them just like
how I configure IBGP(if within the same sub-AS), or EBP(if within different
sub-AS). The only one more thing I need to do on the router is to assign a
real AS number on it.
Maybe you are asking should you specify a neighbor's IP address which
belongs to the same AS#, but a different sub-AS#? I don't think it's a
normal practice. Just like in EBGP, neighbors are usually required to be
directly connected.
