rlOspfv3IfMtuIgnore
Module: RADLAN-OSPFV3-MIB
OID (symbolic): RADLAN-OSPFV3-MIB::rlOspfv3IfMtuIgnore
OID (numeric): 1.3.6.1.4.1.89.216.8.1.31
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This object controls whether DC-OSPF checks the MTU size on incoming Database Description packets. By default, if the received MTU size in a DB Description packet is higher than the MTU size configured on the incoming interface, the OSPF adjacency will not be established. If the interface is tunneled over, say, an MPLS network, then the administrator may not know the maximum MTU size and so can tell DC-OSPF to ignore the MTU size on incoming DB description packets.
What is rlOspfv3IfMtuIgnore?
This controls whether the router checks the MTU size reported in incoming Database Description packets against its own interface MTU. By default a mismatch, a received MTU larger than the local interface's, blocks adjacency formation; admins enable this object to ignore that check, which is useful when the interface is tunneled, say over an MPLS network, and the true path MTU isn't known.
Examples
Walk all instances (SNMPv2c):

Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.89.216.8.1.31.1 snmpget -v2c -c public <target> RADLAN-OSPFV3-MIB::rlOspfv3IfMtuIgnore.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.89.216.8.1.31.1 s <value>
