ignore-mtu-match (MPLS-L2VPN instance view)

Function

The ignore-mtu-match command disables the MTU matching check of the L2VPN on both ends.

The undo ignore-mtu-match command enables the check.

By default, the PE checks whether MTUs of the L2VPN instances on both ends are consistent.

Usage Guidelines

Usage Scenario

In a Kompella VLL networking, if a Huawei device connects to a non-Huawei device that does not support MTU matching check, run the ignore-mtu-match command to configure the Huawei device to ignore the check.

Prerequisites

vpn-target is not configured for the L2VPN instance.

Precautions

By default, a PE checks whether MTUs of the L2VPN instances at both ends are consistent. If not, the VC cannot be in the Up state.

Example

# Ignore the check of MTU of the L2VPN instance named vpn1.

<HUAWEI> system-view
[HUAWEI] mpls l2vpn vpn1
