It only affect traffic via that next hop, but yes. Without a more complete description from the OP it's tricky to say weather that's acceptable or not.
However attaching the problem from a different angle, if all that is needed is a measure of connectivity to the example remote host, then maybe he could use traceroute instead to gather the statistics from. The advantage here is that he could employ traceroute's '-g' option to specify which gateway to use for that probe. /Pete On 24. juli 2010, at 23.14, Philip Guenther wrote: > On Sat, Jul 24, 2010 at 5:30 AM, Pete Vickers <peter.vick...@gmail.com> wrote: >> if your testing host is in the same subnet as the 3 gateways' inside interfaces, then your probe script can just overwrite the ARP entry for the next hop to each of the gateways in turn. no need to do any layer 3 changes at all. > > So you're suggesting that he do it so that each change affects all the > processes on the system and all network connections instead of > limiting it to the pings that need the change?
