You will need to disable ip routing on the client and also use ip gdp irdp.

                Hi,

                Could you please send us your client router configuration? I
couldn't make
                it work as a IRDP client although the ICMP messages were
received but not
                processed. I tried both 'ip irdp' enabled and disabled in
the client
                interface and none work. I had disabled proxy-arp since IRDP
is supposed to
                provide a default router.

                My copnfig in rhe IRDP "server" is:

                interface fastethernet 0/0
                 ip irdp
                 ip irdp maxadvertinterval 10
                 ip irdp preference 50

                And in the client router

                interface ethernet 0
                 ip irdp

                I tried both ip routing disabled with ip host-routing
enabled and ip routing
                enabled alone but none worked.

                Any suggestion?

                Thanks

                Jose Angel

                I used router as a host and it definatly showed me the
                result i said before, However i did not test with a pc
                client, I don't see any difference in the pc behaviour
                but i will test, Unless microsoft implements tcp/ip in
                a different way ;-), I will definatly try a host pc
                doing the same thing to confirm, thanks for the
                update.
