Geert,
I've never really understood the practical point of running a single full
bgp routing table, as all the routes will be installed by default.
Most live implementations of bgp will see routers receiving multiple full
bgp tables from either transit providers or border routers, and using the
bgp algorithm to work out which one to use...
But a full global table is about 135000 routes at the moment (see the CIDR
report to point the finger at non-aggregators), which is too much for 128MB
(after you've used some for IOS, etc.)
Also, little things like bgp 'soft-reconfiguration inbound' have memory
implications, which can increase the requirements.
