I'm new to SNMP. Is there an equivalent in SNMP to "show ip route" on a Cisco 10K router?

RFC1213-MIB has an ipRouteTable tree containing the IP routing table:

[draytm01@mgt03 ~]$ snmpwalk -v 1 192.168.212.45 .1.3.6.1.2.1.4.21
RFC1213-MIB::ipRouteDest.0.0.0.0 = IpAddress: 0.0.0.0
RFC1213-MIB::ipRouteDest.192.168.212.0 = IpAddress: 192.168.212.0
RFC1213-MIB::ipRouteIfIndex.0.0.0.0 = INTEGER: 4
RFC1213-MIB::ipRouteIfIndex.192.168.212.0 = INTEGER: 4
RFC1213-MIB::ipRouteMetric1.0.0.0.0 = INTEGER: 1
RFC1213-MIB::ipRouteMetric1.192.168.212.0 = INTEGER: 0
RFC1213-MIB::ipRouteNextHop.0.0.0.0 = IpAddress: 192.168.212.1
RFC1213-MIB::ipRouteNextHop.192.168.212.0 = IpAddress: 0.0.0.0
RFC1213-MIB::ipRouteType.0.0.0.0 = INTEGER: indirect(4)
RFC1213-MIB::ipRouteType.192.168.212.0 = INTEGER: direct(3)
RFC1213-MIB::ipRouteProto.0.0.0.0 = INTEGER: local(2)
RFC1213-MIB::ipRouteProto.192.168.212.0 = INTEGER: local(2)
RFC1213-MIB::ipRouteMask.0.0.0.0 = IpAddress: 0.0.0.0
RFC1213-MIB::ipRouteMask.192.168.212.0 = IpAddress: 255.255.255.0
RFC1213-MIB::ipRouteInfo.0.0.0.0 = OID: SNMPv2-SMI::zeroDotZero
RFC1213-MIB::ipRouteInfo.192.168.212.0 = OID: SNMPv2-SMI::zeroDotZero

This is actually from a Linux box but I'd hope Cisco implemented RFC1213-MIB; I can't remember and I don't have any routers to hand.

Thank you. Just what I needed. I also discovered this great Cisco SNMP Object Navigator: tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en –  chardin Jul 17 '09 at 14:48

While not Cisco specific, you can use: .1.3.6.1.2.1.4.21 which corresponds to .iso.org.dod.internet.mgmt.mib-2.ip.ipRouteTable from the RFC1213.mib (check mibdepot.com for a copy).

If you want to search for a cisco specific MIB you might try: http://www.mibdepot.com/cgi-bin/vendor_index.cgi?r=cisco
