Just one thing to remember:
Cisco's BGP implementation is what we call "Scan-Based."
This means per every cycle, router walks through Adj-RIB-in
and updates prefixes accordingly. It is not event-based where
as soon as something happens, an UPDATE/WITHDRAW is sent.
Most activities are scheduled accordingly to scan runs. So
sometimes when you advertise a new network through BGP and
wonder why its not advertising for ~30 seconds or so, you
know why :)
Sometimes you may get faster result by doing 'clear ip bgp * in'
before doing 'out.' That should update the adj-rib-in I think.
Of course after you refresh 'in', you gotta refresh 'out.'
Also note that 'soft-reconfiguration inbound' is no longer
necessary when you use routers that support Route Refresh
capability (most routers today do. chances are your IOS
version also does). With full internet routing table,
'soft-recon inbo' will waste a good chunk of RAM on your
router for its usefulness that is already covered by
route refresh.
