Monitoring OSPF

[Ruben Laban]

Hi list,

I was wondering if there's a sane method to keep a realtime eye on OSPF. More 
specifically, getting notifications for link/state/topology/etc changes. So far 
all I could think of is using birdc(6) every x seconds/minutes and comparing 
the output with the previous run to detect changes. Possibly the (debug) log 
could be of service here as well, but have not yet looked into that in detail.
Any pointers would be welcome.

Regards,
Ruben Laban
