No. Re-read my posting above. When you setup a network interface, you give it an address. If you ping an address used by a network interface, the traffic will handled internally, and not be sent anywhere. For example: haven# hostname haven.uniserve.com haven# ping haven.uniserve.com PING haven.uniserve.com (198.53.215.121): 56 data bytes 64 bytes from 198.53.215.121: icmp_seq=0 ttl=255 time=0.493 ms 64 bytes from 198.53.215.121: icmp_seq=1 ttl=255 time=0.481 ms 64 bytes from 198.53.215.121: icmp_seq=2 ttl=255 time=0.495 ms 64 bytes from 198.53.215.121: icmp_seq=3 ttl=255 time=0.480 ms ^C --- haven.uniserve.com ping statistics --- 4 packets transmitted, 4 packets received, 0% packet loss round-trip min/avg/max = 0.480/0.487/0.495 ms haven# Tom
