The ATMARP as used for CLIP (RFC1577) uses the same structure
as the well-known arp.
(There are special opcodes because for ATM a resolution
of hardware addresses to protocol addresses is needed -
I hope Ignatious' work will ease support for ATMARP.
But i consider it not easy to put ATMARP into the existing ATM
framework. CLIP is only one option how to use ATM connections.
IMHO there is a layer necessary between ATM and the IP
encapsulation which multiplexes between the different uses of
ATM VCs. It's a challenge to implement this without performance
There is a special ARP variant fir LAN emulation (LEARP)
which is rather different.
