RFC1213-MIB tem uma árvore ipRouteTable
contendo a tabela de roteamento IP:
[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::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
Na verdade, isso é de uma caixa do Linux, mas espero que a Cisco tenha implementado o RFC1213-MIB; Não me lembro e não tenho roteadores à mão.
