There are 3 options to configure EoMPLS on 6500/7600: - Port mode: xconnect is configured directly on the port - Sub-interface mode: xconnect is configured on a subinterface (gig0/0.100), using dot1q VLAN to match traffic - SVI (interface vlan): xconnect is configured on SVI
The first 2 options do not require special HW, and do not perform MAC learning (they do consume an internal VLAN, and the VLAN used for the sub-interface is globally used on the device) The SVI option requires a WAN card (SIP/ES) on the core facing side, and it would perform local MAC learning, as the SVI can be attached to multiple local interfaces.
