I didn't know about the ptp thing. That's nifty.

A cisco FDDI-PA can talk both in a 7500 or old 7200 (the VXR don't
support the FDDI cards but the VIP does ).

About that, Peter...is there ANY way to get a FDDI PAM to run in a
7206VXR?   Or will it just plain not work, ever?


I thought PAs were compatible across all chassis?   Maybe in a VXR with
an STD NPE?

  No, not all PAs are supported in all chassis.   I think that was
Cisco's way of forcing premature obsolecense on some things.
