OSPF: SNMP ifIndex Value for Interface ID in OSPFv2 and OSPFv3 Data Fields

Configuration Examples for OSPF: SNMP ifIndex Value for Interface ID in OSPFv2 and OSPFv3 Data Fields

Cisco IOS Release: Multiple releases

Configuring the SNMP ifIndex Value for Interface ID for OSPFv2: Example

The following example configures the OSPF interfaces to use the SNMP ifIndex values for the interfaces
IDs. The show snmp mib ifmib ifindex command confirms that the SNMP MIB-II ifIndex values are
used for the Interface ID values in the OSPFv2 data fields.

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)# router ospf 1

Router(config-router)# interface-id snmp-if-index

Router(config-router)# ^Z

Router# show ip ospf 1 1 data router self

Configuring the SNMP ifIndex Value for Interface ID for OSPFv3: Example

The following example configures the OSPFv3 interfaces to use the SNMP ifIndex values for the
interface IDs.

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)# ipv6 router ospf 1

Router(config-router)# interface-id snmp-if-index
