you need to enable
ip route profile
later you can check with
sh ip route profile
Hope to help
However, this feature does not notify me what's or when route is added or deleted. This command does not count deletion, only counts addition.
Anyone else knows a way to monitor routing table changes? What's added and what's deleted and notify the NOSC via SNMP or syslog?
If your IOS supports it, you may look into EEM
You may need some customization and maybe rely on the MIB for that kind of tracking.
Unfortunately I don't know how to do Perl/Expect scripting.
Now I am looking at RANCID to perform "show ip route" and email me the difference. That could be another way to do it.
I just can't believe there are no easy way to monitor routing table. Don't people monitor their routing table changes?
RANCID is good too. I used it. RANCID also uses Perl language as well.
The reason you want to use Perl customization is that even if routing does not change but you have routing flap, the perl script can detect the differences in the timestamp. You can write a script so it can send you email even when routing table does not change but flapping as well.
