In a VPLS context on a bridge domain (BD), removes MAC addresses that have been dynamically learned, thus providing faster convergence.
MAC address withdrawal is disabled.
Bridge-domain configuration mode
A MAC address withdrawal message is sent with a MAC list Type Length Value (TLV). 200 MAC addresses are bulked and sent in one MAC TLV message.
Note
The MAC withdrawal support is only for explicit MAC addresses in a MAC withdrawal TLV. An empty MAC list, as well as the sending of a MAC withdrawal TLV to a specific subset of peers, is not supported.The maximum number of MAC addresses supported is 5000 in a 5-second interval. The remaining MAC addresses in the attachment circuit (AC) logical interface (LIF) are not sent. After the 5-second interval, another LIF "down" event triggers a MAC withdrawal message for a new-5 second interval.
MAC withdrawal is supported for both VPLS and MCT-VPLS. MPLS signals the MAC withdraw TLV to all the peers.
Use the no form of this command to disable MAC address withdrawal.
The following example enables MAC address withdrawal on a BD.
device# configure terminal device(config)# bridge-domain 10 device(config-bridge-domain-10)# mac-address withdrawal
The following example illustrates output of the show bridge-domain command confirming that withdrawal is enabled.
