hwOspfv2NbrIfMtu
Module: HUAWEI-OSPFV2-MIB
OID (symbolic): HUAWEI-OSPFV2-MIB::hwOspfv2NbrIfMtu
OID (numeric): 1.3.6.1.4.1.2011.5.25.155.6.1.8
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This object indicates the size of the largest IP datagram that can be sent out the sending interface without fragmentation. It is obtained from the DD packets from this neighbor. By default, the value is 0. The MTU of the interface should be set to 0 in the DD packets when the MTU is not enabled on the OSPF interface.
What is hwOspfv2NbrIfMtu?
The largest IP datagram size this neighbor can send without fragmentation, as learned from its Database Description packets; reads 0 both by default and when MTU checking isn't enabled on the neighbor's OSPF interface, so an MTU mismatch during adjacency formation is a classic thing to check here.
