Instead of pinging (and all the IP and ARP headaches that involves), I'd suggest using a multicast or broadcast message sent to ethertype 9000 (loopback). If the other interfaces can hear your message, then they're in the same Ethernet broadcast domain, and can (and probably should) be IPMP'd together. -- James Carlson, KISS Network <james.d.carlson at sun.com> Sun Microsystems / 1 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677
