IP Route

[12122053]

I have setup back to back between a 1604 and 2524 routers. Im using RIP for my routing protocol. On the 1604 router i have a isdn interface that i use for the internet. The problem im having is when i place the command ip route 0.0.0.0 0.0.0.0 s0. After i place the command none of my client machines can't access the internet it seems that there going through the s0, but don't i need that command in order for my 1604 hosts to reach 2524 hosts. Currently I have ip route 0.0.0.0 0.0.0.0 d1 which works fine, but i can't ping from a host on the 1604 side to the 2524 side. Any suggestions, thanks.

The problem is your router now sees the default route as being available both through s0 and dialer1 equally. Your router will round-robin packets between both paths.

You need to weight them so that one is favored:

ip route 0.0.0.0 0.0.0.0 s0 10
ip route 0.0.0.0 0.0.0.0 dialer1 15
