snOspfRouterId

Module: FOUNDRY-SN-OSPF-GROUP-MIB

OID (symbolic): FOUNDRY-SN-OSPF-GROUP-MIB::snOspfRouterId

OID (numeric): 1.3.6.1.4.1.1991.1.2.4.1.1

Node type: OBJECT-TYPE

Type: RouterID

Access: read-write

Description: A 32-bit integer uniquely identifying the router in the Autonomous System.

By convention, to ensure uniqueness, this should default to the value of one of the router's IP interface addresses.

What is snOspfRouterId?

The 32-bit OSPF router ID for this device, conventionally set to one of its IP interface addresses so it stays unique across the autonomous system. Admins set this explicitly on multi-homed routers to avoid ID collisions that would otherwise break adjacency and LSA origination; for example, setting it to a stable loopback address like 10.0.0.1 keeps the router ID consistent even if physical interfaces flap.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1991.1.2.4.1.1
snmpwalk -v2c -c public <target> FOUNDRY-SN-OSPF-GROUP-MIB::snOspfRouterId

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1991.1.2.4.1.1.1
snmpget -v2c -c public <target> FOUNDRY-SN-OSPF-GROUP-MIB::snOspfRouterId.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1991.1.2.4.1.1.1 s <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> snOspfRouterId.1
