SNMP and BGP

Thu Mar 21 23:24:35 UTC 2002

The snmp root for BGP is .1.3.6.1.2.1.15 with the specific OID for which 
peer gave you the prefix at .1.3.6.1.2.1.15.6.
There is also come stuff under enterprises.cisco but not much more info or 
at least I can't figure out where anything really useful is in the cisco 
bgp mib. (anyone else??)
I will send you the generic MIB file if you need it. Its on the cisco site 
listed as BGP4-MIB-V1SMI.my

I warn you to NOT do an snmpwalk on that table on a router with multiple 
full routing tables, it can take forever and will push the CPU on the 
router to the max (not a happy thing). Load a router with a partial table 
and poll that to test it out. Or if you just want what actually makes it 
into the routing table you might want to look at . 1.3.6.1.2.1.4.21.1 .
Enjoy.
