Telco ATM to Frame conversion

[BIKEMAN]

Hi all   I'm currently desgning a network with 200 sites connecting via frame relay to the three core sites with the core being a fully meshed ATM switched network (Xylan layer 2 and 3 ATM switches).   What I'm wondering about and haven't had much luck finding out from the telco's is whether inverse arp will still be working ? My opinion is that the inverse arp might have some problems - with the layer 3 switches I think things might get a little complicated (I am disabling inverse arp on the routers)   I realise this depends mostly on what the telco is doing to convert the frame to ATM, but any info or anecdotes you might have about similar things would be welcome.   Regards   Rudi Meyer
