From your description, I think you're saying that you're sending
routes to a receiver who isn't injecting them into the table?
Enable soft-reconfiguration inbound to check whether it's still
receiving all the routes ('neighbor a.b.c.d soft-reconfiguration
inbound') then
Check this with 'sh ip bgp <neighbor> received-routes'. Then cross
reference with 'sh ip route bgp' to see what's getting in. if you're
getting them,
check the next hop being advertised is available. If the next hops
being advertised aren't reachable, then make sure the advertising
router is
set to 'next-hop-self'.
HTH and apologies if I'm off target..

I'm new with the 4506 so this may be an obvious problem.
In my case I have one 4506 that I'm using the layer 3 routing
option. I'm trying to send 1 full BGP feed for now for the purposes
of testing, eventually I'll add another to make the excersize
meaningful. My problem is this, when I turn up the session after a
few seconds up to a minute the routes withdraw and when I do a show
ip BGP a.b.c.d I see the route entry and it's indicated to have no
path available unaccessible. When the routes first install they
have the path available and work. In parallel, I'm noticing a
series of IP Cef Distributed errors concerning low memory. (no bgp
log messages)
So, am I seeing a limitation in the number of routes I can install?
The cpu shows 512 megs installed, isere a software limit that I'm
bumping in to?
The switch is running 12.1-19 ?
Is this a hardware / memory issue or should I check in other areas?
What would make a bgp table full of routes remove once the table is
downloaded?
Thank you
Scott
P.S. Sorry if this is a n00by question, the 4506 is a new switch in
my lab and google hasn't yielded me to many usable pointers yet.
