depends on how you're set up.
on the interface:
map-group 1
in global config:
map-list 1
ip 198.103.x.x atm-vc 1 broadcast <== next hop
should get you pingable
but if you're using sub-interfaces then:
on the interface:
interface ATM1/0.2 point-to-point
ip address 198.103.x.x 255.255.255.252
no ip directed-broadcast
atm pvc 2 0 172 aal5snap 10000 10000
it just doesn't happen by putting an address on the interface.
also, remember that ATM passes cells, if you want to get ip stats from it
then you will have to make a BVI. Here is an example on one of our lab
routers.
LabR05#sh ip arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet 198.103.x.x - 00e0.b03f.fc40 ARPA Ethernet2/0
Internet 198.103.x.x 65 0800.2bb3.19b5 ARPA Ethernet2/0
Internet 198.103.x.x - 00e0.b03f.fc41 ARPA Ethernet2/1
Internet 198.103.x.x 1 0000.0c3f.026b ARPA Ethernet2/0
Internet 198.103.x.x - 0000.0c49.2958 ARPA BVI1
Internet 198.103.x.x 207 0050.7338.7401 ARPA BVI1
Internet 198.103.x.x 7 0010.5a89.bbdf ARPA Ethernet2/0
Internet 198.103.x.x 1 0000.b450.4554 ARPA Ethernet2/0
Internet 198.103.x.x 2 0060.089e.09f0 ARPA Ethernet2/0
Internet 198.103.x.x 1 00e0.14cc.6300 ARPA Ethernet2/0
Internet 198.103.x.x 0 0800.2085.7c7a ARPA Ethernet2/0
here you can see that the BVI definitely responds to IP.
hope this gives you a few ideas.
