The mtu-match ignore command configures an EVPL instance to ignore the MTU matching check.
The undo mtu-match ignore command disables an EVPL instance from ignoring the MTU matching check.
By default, an EVPL instance cannot ignore the MTU matching check.
Usage Scenario
By default, PEs perform the MTU matching check for EVPL instances. If the MTUs of the EVPL instances on the PEs at both ends do not match, the VC cannot go up. If a Huawei device needs to communicate with a non-Huawei device that does not support the MTU matching check for EVPL instances, run the mtu-match ignore command to ignore the MTU matching check.
