How to disable MTU verification on Ruijie Switches?

When receiving a database description packet, OSPF verifies whether the MTU of the neighbor's interface is

the same as that of its own interface. If the interface MTU specified in the received database description packet is greater than the MTU of the local interface, the neighbor relationship cannot be set up. To resolve this problem, you can disable MTU verification:

Disable Command(disable by default):

Ruijie#configure terminal

Ruijie(config)#int gigabitEthernet 0/9

Ruijie(config-if-GigabitEthernet 0/9))#ip ospf mtu-ignore

Enable command:

Ruijie#configure terminal

Ruijie(config)#int gigabitEthernet 0/9

Ruijie(config-if-GigabitEthernet 0/9))#no ip ospf mtu-ignore
