If you are trying to disable mac-address learning on VPLS, only way to do is to limit the VLAN mac-addresses globally. (Limit the vlan where u gave the command xconnect vfi).

You can control mac-address learning for a VLAN by using this switchport command on a trunk.

Router(config-if)# switchport port-security maximum 3 vlan 102

Or simply use this to allow only a certain number of mac's per access port.

Router(config-if)# switchport port-security maximum 1

Here is the command reference.


PS: you cannot totally stop mac learning as the valid values are from 1-4097 so you cant set it to zero and i believe you dont want to as well , since you have a layer2/3 environment.
