ospfv3RouterId
Module: OSPFV3-MIB
OID (symbolic): OSPFV3-MIB::ospfv3RouterId
OID (numeric): 1.3.6.1.2.1.191.1.1.1
Node type: OBJECT-TYPE
Type: Ospfv3RouterIdTC
Access: read-write
Description: A 32-bit unsigned integer uniquely identifying the router in the Autonomous System. To ensure uniqueness, this may default to the 32-bit unsigned integer representation of one of the router's IPv4 interface addresses (if IPv4 is configured on the router).
This object is persistent, and when written, the entity SHOULD save the change to non-volatile storage.
What is ospfv3RouterId?
A 32-bit value that uniquely identifies this router within the OSPFv3 Autonomous System, commonly set to one of the router's own IPv4 addresses (e.g. 10.0.0.1) even though OSPFv3 itself routes IPv6. Admins set this explicitly on multi-router networks to guarantee it's unique, since a duplicate router ID breaks route computation; it is read-write and persists across reboots.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.191.1.1.1 snmpwalk -v2c -c public <target> OSPFV3-MIB::ospfv3RouterId
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.191.1.1.1.1 snmpget -v2c -c public <target> OSPFV3-MIB::ospfv3RouterId.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.191.1.1.1.1 s <value>
