My understanding is the route is valid as long as the interface is up; just like adding a secondary IP on the interface. Ralph Doncaster principal, IStop.com On Mon, 7 Oct 2002, Alex Rubenstein wrote:
Aha. So, if you route to a ethernet interface, it will try to arp for that address on that subnet, even without having a local address on the same subnet? This seems to me to be something you don't want to do. Is the entire route valid as long as the router can ARP for one of the addresses in the routed subnet?

As in, the next hop is still truly undetermined. I guess I don't know this because I've never tried it. But, how does the router determine where to send the packets for a route statement as specified above (ip route a.b.c.d e.f.g.h f0/0) ?When you setup a secondary ip on an interface int fa0/0 ip address a.b.c.d e.f.g.h secondary How does it determine where to send the packets? ARP. Which is the same as adding the route described above. -Ralph-- Alex Rubenstein, AR97, K2AHR, alex () nac net, latency, Al Reuben -- -- Net Access Corporation, 800-NET-ME-36, http://www.nac.net --
