It's been delayed time and again, but I've finally found the time to push
through the docs and configuration notes needed to get our ASN up and
running with our upstream providers.
So, this morning we began announcing ASN 18506 and our netblocks out
Sprintlink with no problems. I had them turn on full routes and we're up
to: '11176 network entries and 11169 paths' and still climbing.
Ok, so hears the setup:
UUNET - [T1/FR] - s0/0.1 2621 s0/1 - [T1] - s0/1 3640 s1/2 - [T1] - Sprint
I'm still trying to get our Accounts Payable folks to get us our UUNET
account number so I haven't got any BGP communications up with UUNET yet.
As the 2621 is maxed at 64mb RAM, I'm going to tell UUNET to only send me
customer routes. Also, presently I'm filtering non-iBGP info from the 3640
to the 2621 and only allowing Sprint's own ASN through (eventually I'll have
it pass Sprint and their customers). The 2621 shows all the 1238 netblocks
that should be getting through in the bgp table, but if I do a 'sh ip route'
they don't appear, and in fact no BGP routes show.
Here's the pertinent current config sections:
