Re: [PWE3] new draft - Extension to LDP-VPLS for Ethernet broadcast &multicast

Simon,

If this is the case, some kind of filter needs to ensure only broadcast and multicast use the p2mp PW, while unicast and unknown unicast uses the p2p PW.

Bonjour Thomas,

Our current thinking is that unknown unicast frames should behandled as per
RFC 4762 (e.g flooded on the P2P PWs). What do you think?

BTW, any feedback on the following two questions:

- whether there is a need to optimise Ethernet broadcast/multicasttraffic
when using VPLS.

- whether carriers with LDP-VPLS (RFC 4762) would like to considera
solution that does not require BGP.

Thanks,

Simon
