BGP VPNv4 Peer Table

clark.adam.p
Level 1
Level 1

Hey all,

  Is there a way that the BGP VPNv4 peer table can be monitored like the global BGP table (1.3.6.1.2.1.15)

[root@lenny ~]# snmpwalk -v 2c -c snmpro 192.168.255.129 -m all 1.3.6.1.2.1.15
BGP4-MIB::bgpVersion.0 = Hex-STRING: 10
BGP4-MIB::bgpLocalAs.0 = INTEGER: 64750
BGP4-MIB::bgpPeerIdentifier.192.168.255.130 = IpAddress: 192.168.255.130
BGP4-MIB::bgpPeerIdentifier.192.168.255.131 = IpAddress: 192.168.255.131
BGP4-MIB::bgpPeerIdentifier.192.168.255.132 = IpAddress: 192.168.255.132
BGP4-MIB::bgpPeerState.192.168.255.130 = INTEGER: established(6)
BGP4-MIB::bgpPeerState.192.168.255.131 = INTEGER: established(6)
BGP4-MIB::bgpPeerState.192.168.255.132 = INTEGER: established(6)


ROUTER#show ip bgp vpnv4 all summary

Neighbor        V    AS MsgRcvd MsgSent   TblVer  InQ OutQ Up/Down  State/PfxRcd

192.168.255.132 4 64750     139     142        8    0    0 02:15:43        0

Notice that the 10.98.128.222 peering is not in the global BGP table that SNMP reads?

The closest that I can get is to put a threshold on the amount of prefix recieved via a peering:

CISCO-BGP4-MIB::cbgpPeerAcceptedPrefixes.10.98.128.222.ipv4.vpn = Counter32: 1

CISCO-BGP4-MIB has no table contructs that resemble the ones in BGP4-MIB

Cheers

You need an image with the fix for CSCso90107.  The fix for this bug implemented BGP VPNv4 peer support in the BGP4-MIB and CISCO-BGP4-MIB.  To get such an image, you would need to move to 12.4(15)T9 or higher for your platform.
