BGP Configuration

Hi everybody,

I'm having trouble to put a BGP config in working state.

I keep receiving this log messages (show log swlog)

Apr 23 11:53:00 ALU_6900 swlogd: bgp_0 peer info(5) BGP Neighbor [peer1,xxxxx] in VRF 0 transitioned to ESTABLISHED state.
Apr 23 11:53:01 ALU_6900 swlogd: bgp_0 updrx error(2) [peer1,xxxxx] UPD msg validation failed. ret 2
Apr 23 11:53:01 ALU_6900 swlogd: bgp_0 errors error(2) [peer1,xxxxx] Rcvd Bad Update msg!
Apr 23 11:53:01 ALU_6900 swlogd: bgp_0 peer info(5) BGP Neighbor [peer1,xxxxx] in VRF 0 transitioned to IDLE state.


My config:
! BGP:
ip load bgp
ip bgp autonomous-system 263319
ip bgp log-neighbor-changes
ip bgp network 177.52.173.0 255.255.255.0
ip bgp network 177.52.173.0 255.255.255.0 admin-state enable
ip bgp neighbor 1.2.3.4
ip bgp neighbor 1.2.3.4 remote-as xxxxx
ip bgp neighbor 1.2.3.4 description "peer1"
ip bgp neighbor 1.2.3.4 md5 key-encrypt 599486d8dc3c4b0b461cdba297552eb8
ip bgp neighbor 1.2.3.4 ebgp-multihop 8
ip bgp neighbor 1.2.3.4 update-source "peer1_iface"
ip bgp neighbor 1.2.3.4 admin-state enable
ip bgp admin-state enable


Does anyone know what can be happening? Or were can i find more detailed logs of the protocol so i can debug easily?

Thanks!

If you take off the MD5 key on both sides, does it come up?

The same happens. I think the problem isn't with the MD5. Connection is ESTABLISHED, some routes are downloaded, but when maximum-prefix is reached, instead of ignoring the new routes, it deletes the routes and restarts the peer.

When i increase the maximum-prefix, the switch reboots.
