[isp-bgp] Re: Routing Information

["Serge Paquin" <isp-bgp@...>]

When using IBGP internally is it typical to use internal AS#'s for the
internal routers/switches or do you use them all with your AS# and the
next-hop parameter?

I'm thinking that it may be wise for me to have my Layer3 Switch advertise
my address blocks to my routers.  That way the routers will advertise to
each other also.

Serge.
