[nsp] ATM switching on a 7200

[Bob Collie]

Agreed; however you can do Frame Relay switching on the 7200 as well as
FR-ATM and vice versa Internetworking at the packet level, so why can't
you do ATM switching?

Anyone from Cisco on the list?

Hi,

Correct me if i'm wrong but i don't think a router can switch a cell
based only on the vp value,due to the fact that it has to turn cells
into a packet as it receives them from an ATM interface,segment it again
into cells and transmit out to an ATM interface.The router needs an ip
address to bind the packets into a pvc,or some sort of bridging between
ATM interfaces which i don't think is working for a whole vp. A possible
solution could be to terminate (rather than trying to cell
switch) the pvp's on the router sw7200 interfaces and cef-switch on the
individual pvc's.

Regards

Kostas
