Hey Wang,
Don't feel badly. Many who have gone before you found the ATM documentation
very confusing. But, here's what you should keep in mind.
ATM works in a way similar to frame relay.
You can statically map the remote ip address to the local pvc or you can
allow atm to so dynamically. So, your assumption is incorrect. ATM will
dynamically map the remote ip address to your pvc.
What you need to keep clear in your head is the difference between dynamic
mapping for pvc's versus SVC's. With SVC's, you have to define an
arp-server. With PVC's, you don't.
HTH, Tim

Subject: silly ATM question maybe..
> With so many experts on this wonderful list, I like to ask another
question. I am a little bit confused by reading configuring ATM.. Regarding
ATM PVC, one is static and another is dynamic. Can I assume that this is
similar to frame-relay map and invers-arp? The impression I have is that ATM
will not work by simply configuring the IP address and PVC in the interface
so I always have to use the static map to reach other end.
