dear all,
i have the folwoing scenario :
Router 1 Router 2
E0(10.20.1.1) S0(1.1.1.1)-------------------->s0(1.1.12) --- E0 10.40.1.1
S1(2.2.2.1) ---------
-------
------->
S0 (2.2.22) Router 3 --- E0 10.50.1.1
i do have my routing table in Router 1 look like this:
S 10.40.0.0 [1/0] via 1.1.1.2
S 10.50.0.0 [1/0] via 2.2.2.2
C 10.20.0.0 is directly connected, Ethernet0/0
1.1.1.0/30 is subnetted, 1 subnets
C 1.1.1.0 is directly connected, Serial0/0
2.2.2.0/30 is subnetted, 1 subnets
C 2.2.2.0 is directly connected, Serial0/1
S* 0.0.0.0/0 [1/0] via 10.20.1.10
the last static route (default route) is directed to our proxy (10.20.1.10) that means all IP packets not handled by Router 1 routing talbe will be forwarded to proxy.
now my problem is that if anyone of this branch link goes down (eg, router 2 link) router 1 is transferring all packets to my proxy and huge network usage is happening on my proxy. i need to force a route destined to network 10.50.0.0 through one path only. if that link down, drop the packet. dont re-route to the default route.
How can i do this. if any onw knows please help me.
Regards
Mohamed

sorry the my diagram was not good, try to see this,
Router 1------------------------------- Router 2--------------- -- Router 3
E0(10.20.1.1) ------------------------ E0(10.40.1.1)------------E0(10.50.1.1)
S0(1.1.1.1) ---------------------------- S0(1.1.1.2) --------------- S0(2.2.2.2)
S1(2.2.2.1)

Mohamed,
I suggest that you put the following route in all routers:
ip route 10.0.0.0 255.0.0.0 null0 200
This will make all packets to a private network that is unreachable get dropped by the routers without forwarding them to the proxy server.
Good luck.

You could also try
ip route 10.50.0.0 255.255.0.0 2.2.2.2 permanent.
This will make the route to stay in the routing table even when the link goes down.
