Don't think he did, Alec. Using communities would make it
much easier to filter the routes to the customer than
using confederation. I don't think there's any need to
implement confedrations here. Sounds like headaches I
don't need. Communities would allow you to filter very
specifically only routes coming from the router.
The real problem here is that the ISP with the EBGP
session still depends on the ISP with the IBGP session to
do things correctly, unless customer routes are filtered
at a network level -- Something I've never liked doing,
but always felt was necessary.
How can I have a setup that is flexible enough to satisfy
my customer (and my workload) but safe for me? I've had
customers running OSPF with one of my routers that was
redistributing OSPF into BGP, and it was probably one of
the stupidest mistakes I've ever made. Screwed me when
some dumbass decided he could use whatever networks he
wanted on the Sun they were running gated on.
