Hello,
I have a Juniper M120 router running JUNOS 9.6R1.13. The SNMP trapping behavior on this device seems to differ from the Cisco routers I've worked on when it comes to the bgpBackwardTransition trap.
On a Cisco, when a BGP session is dropped, it will send one bgpBackwardTransition trap. Upon it's reconnection, it will then transmit a bgpEstablished trap.
On the Juniper, it will transmit a bgpBackwardTransition trap when the session is dropped. However, where it differs is that it will re-transmit the trap each time it cycles the BGP states in an attempt to re-connect the downed session.
Is this intended functionality? Has anyone else experienced this?
Cheers,
Christoph
