RE: [RPRWG] OK, we heard them talk, but what did they SAY?




What you mention is related to a presentation on 
encapsulation bridging where SRC/DEST is encapsulated
further into another SRC/DEST (MAC-in-MAC) allowing
encap bridging on the edge and transparent in the core.
This is one way of muxing/demuxing at the edges but it's
one approach not particularly focused on the existing
customer VLAN implementation.

To a certain degree, CID will influence encap bridging
approaches and any handoffs to L2.5 and L3.
