Joe,
Good example of CLIP w/SVCs. BTW, according to the Cisco docs CLIP can be
used with PVCs and inverse ARP. The configuration is a bit different than
the one you provided of course.
Details Here:
http://127.0.0.1:8080/cc/td/doc/product/software/ios113ed/113ed_cr/wan_c/wca
tmnpm.htm#xtocid587824
Note that even though works with ATM Inverse ARP (i.e., a dynamic L3 to L2
address mapping) , other protocols, most notably AppleTalk, do not and
require a static mapping via the map-list and map-group commands.
HTH,
Mike McSpedon
