I have a fairly complex routing set-up with mutual redistribution between BGP and EIGRP. I would like to monitor any kind of change in the routing table, or the underlying databases (BGP table, EIGRP topology) by using SNMP (similar to monitoring the router's CPU). Also, because it's a handy means to quickly identify other problems in the network.
Currently I have only found two relevant OIDs, i.e. cEigrpTopoRoutes and ipCidrRouteNumber. I am polling these values every 10s.
Are there any other relevant values? Most of the MIBs have the full tables, while I only need "summary" values.
I am particularly interested in the "equivalent" of the IOS commands:
show ip route summary
show ip bgp summary
With the OIDs found so far, it's not very clear on how they relate to the output of the commands above.
in the output of the show ip route summary command there is a line indicating "internal". The documentation says that these are routes that are not owned by any routing protocol, but where do those routes actually come from?
