Really helpful to the guy aren't you? He has local ATM - he has wide area ATM and asks a question about the best way to link? And you suggest he uses different technology!! Ok I suggest the best way is connect an extra line from asx200 to an extra line asx1000 directly. The router connects as before to both switches. Usual IP will still traverse the router, but direct ATM applications can do direct ATM connections, certainly using PVCs (if you can handle coping the various management domains :-) and maybe using signalling depending on whether and what the WAN ATM uses for signalling. Also you may be able to get IP addresses from the IP network that links the WAN connected routers, so that you can configure a second virtual IP interface on any ATM connected hosts so that their IP traffic avoids the local router. When/if NHRP (or similar) etc etc gets deployed - it may be possible to do all this a little simpler - at least for small numbers in trials!!
