Gordon,

I'm using Nagios's check_bgp plugin to monitor our BGP sessions and it's 
working great.  Your OID is correct.  I sniffed a query from my NOC 
server and see that it's querying 1.3.6.1.2.1.15.3.1.2 on one of our 
7600s running SRB and is getting a response from 
1.3.6.1.2.1.15.3.1.2.a.b.c.d where a.b.c.d are the IPs of the remote BGP 
peers listed once per entry in the bulk SNMP response.

I believe the problem is your method of querying.  I take it that you're 
using a simple snmpget, correct?  Try snmpwalk on the base OID instead. 
    snmpget does a SNMP get-request (or a single exact match request) 
whereas the snmpwalk does a get-next-request or a bulk request.  A SNMP 
buff could explain it better than I but that's the gist of it.
