  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
