MAC-Learning in EoMPLS

Unanswered Question
Dec 5th, 2007

I was wondering if in a EWS circuit, does the MPLS PE Router learn the MAC-Address or is it dependent on the way the Circuit is configured i.e. Type-4 and Type-5 or Sub-interface based or SVI based.

Is there any way this MAC-learning can be disabled...Also, if MAC-learning is enabled does this have a direct impact on the number of MAC-addresses I can learn in any other service like VPLS or ERS etc....

I have this problem too.

PE should not and does not need to learn MAC-address for EoMPLS, this is irrelevant of circuit type.

Cat6K has mac-limiting feature which you can limit the number of MACs can be learned on per-vlan bases.

MAC learning is only required if you need local switching, which requires a SIP or an ES20 card.
