The mpls l2vpn mac-withdraw disable command disables the VLL from sending MAC Withdraw messages on a VPLS network with primary and secondary VLLs.
The undo mpls l2vpn mac-withdraw disable command restores the default setting.
By default, the VLL is enabled to send MAC Withdraw messages on a VPLS network with primary and secondary VLLs.
Usage Scenario
In a VPLS scenario with primary and secondary VLLs, the primary and secondary VLLs send MAC Withdraw messages to the VPLS-enabled RSG each time a primary/secondary PW switchover is performed. After receiving the MAC Withdraw messages, the VPLS-enabled RSG clears all learned MAC addresses. Then packets will be transmitted in broadcast mode. To prevent packets from being broadcast, run the mpls l2vpn mac-withdraw disable command to disable the VLL in Ethernet or VLAN encapsulation mode from sending MAC-Withdraws messages during a primary/secondary PW switchover.
Precautions
This command takes effect only in a VPLS scenario with primary and secondary VLLs. In other scenarios, do not run the mpls l2vpn mac-withdraw disable command; otherwise, services will be interrupted.
