Greetings Tim,
I am not sure what happens on the neighbor statement?
I have used "timers bgp 0 0", which seems to work for me:

Hi guys,
I'm trying to prevent bgp from sending keepalives across an isdn link.
I configured the following on each side:
router bgp 200
bgp router-id 150.1.4.4
bgp log-neighbor-changes
neighbor 130.1.124.1 remote-as 100
neighbor 130.1.234.3 remote-as 200
neighbor 150.1.5.5 remote-as 200
neighbor 150.1.5.5 update-source Loopback0
neighbor 150.1.5.5 timers 0 0 <-- Stop
keepalives
Yet, BGP is still sending keepalives across the link. See debug output
below.
Why is that?
Is there anything I can do to stop these keepalives?
