Configuring VPLS instances

• ON CCEP ports, MAC withdrawal messages are sent only when both local and remote links of
the CCEP goes down.
• On a MCT standby switch, the LDP MAC withdrawal messages are sent to the active switch on
MCT spoke PW and the MCT active switch relays the LDP messages to all the active PWs.
Configuring MAC address withdrawal globally
Use the mac-address withdrawal command at the global configuration mode to enable sending
LDP MAC address withdrawal messages to all VPLS instances.
Brocade(config-mpls)# vpls-policy
Brocade(config-mpls-vpls-policy)# mac-address withdrawal
Syntax: [no] mac-address withdrawal
Configuring MAC address withdrawal per VPLS instance
Use the mac-address withdrawal command at the interface configuration mode to enable sending
LDP MAC address withdrawal messages to specific VPLS instances.
Brocade(config-mpls)# vpls sample1
Brocade(config-mpls-vpls-sample1)# mac-address withdrawal
Limiting the number of MACs withdrawn
Use the mac-address withdrawal-limit command at the global configuration mode to limit the
number of MAC’s withdrawn to all VPLS instances in a five second interval.
Brocade(config-mpls)# vpls-policy
Brocade(config-mpls-vpls-policy)# mac-address withdrawal-limit
Syntax: [no] mac-address withdrawal-limit
Use the mac-address withdrawal-limit num command at the global configuration mode to specify
the number of MACs withdrawn to all VPLS instances in a five second interval.
Brocade(config-mpls)# vpls-policy
Brocade(config-mpls-vpls-policy)# mac-address withdrawal-limit 1000
Syntax: [no] mac-address withdrawal-limit num
The num parameter can be a value between 100-2000. Default value is 500.
Clearing the contents of the VPLS MAC database
To clear the entries stored in the VPLS MAC database belonging to a VPLS instance, enter a
command such as the following.
Brocade# clear mac vpls name v1
Syntax: clear mac vpls name name | id vpls-vcid | ethernet portnum | label label
