Is anyone doing tag-switching on 6500s mixed with cisco router platforms (7xxx, 36xx)? While trying to turn up a 6509 (sup2/msfc2/pfc2) running 12.2(18)SXD3, I've found that while TDP appears to work, our 7500s fail to switch some packets tagged by the 6509. I've been afraid to turn on much debugging on live routers passing large amounts of traffic, the above is about all the detail I have so far.

I'm basically wondering if there's some knob I've not encountered on the router platforms that needs to be set on the 6509 in order for tag-switching to work properly, or if it just doesn't entirely work on sup2/msfc2?
