VPLS has traditionally only been supported on the 7600
platform, specifically, the ES and ES+ line cards.
As you rightly mention, the SUP-2T on the 6500 introduces
support for native VPLS support, i.e., you don't require SIP
or ES line cards on this platform to support VPLS. On the
SUP-2T, VPLS is supported on the integrated PFC4 board.
In case you don't have the SUP-2T, you'll need the ES+ (ES
won't work, only ES+) line cards which are now supported on
the 6500 and 6500-E chassis, equipped with a SUP720-3B,
SUP720-3BXL, SUPVS720-3C or SUPVS720-3CXL supervisor module.
The new 40Gbps-port 6900 line cards for the 6500 also
support VPLS, but these require the SUP-2T supervisor
The WS-X6724 line card you have is what is called a "LAN
card". While it's nice, cheap and dense, it's brain dead. A
lot of the cool features you need with such a line card will
run off the PFC located on the supervisor module, e.g.,
MPLS. So this line card won't give you VPLS, since the
SUP720-3B and SUP720-3BXL don't support it on the PFC3.
I notice that the SUP-2T supports the WS-X67xx line cards,
so it possible that you could get VPLS on them, but I'm not
really sure. Suggest you check with TAC for confirmation,
before you buy.
Hope this helps.
