Rourt-A
ip route 0.0.0.0 0.0.0.0 E0
ip route 192.168.11.32 S0
ip route 192.168.11.64 S1
ip route 192.168.11.32 S1 10
ip route 192.168.11.64 S0 10
Router-B
ip route 0.0.0.0 0.0.0.0 S0
ip route 192.168.11.0 Serial0
ip route 192.168.64.0 Serial1
ip route 192.168.11.0 Serial1 10
ip route 192.168.64.0 Serial0 10
Router-c
ip route 192.168.11.0 S0
ip route 192.168.11.32 S1
ip route 192.168.11.0 S1 10
ip route 192.168.11.32 S0 10
Its is full looped routing that why i used distances
when I down interface from Router-A To Router-B it is accessible Via Router-C
But when i down other interface from Router-A to Router-C it is not accessible Via Router-B
(other interfces is up but not working)
plz chck the routing and suggest ?????? any solutions
I think every thing is ok.. but i dont know where is problem ?????
Thanks

Hi
Do post out a topological diagram on how your routers are connected and also the ip addressing scheme you have assigned on different interfaces..
That will give a fair info on your setup and the requirement you have.
Also a possible routing protocol too can well fit onto your setup avoiding the hassels involved in defining the static routes everywhere..

Hi,
i have given the interface name intead of any next hop ip ,
thanks

Hi Afzaal
do revert back on the connectivity details how Router A , Router B and Router are connected..

Hi
They are connected via E1
A is connected to B & C
B is connected to A & C
C is connected to A & B
i am tring to send yo the diagrams i f avialbe.
thanks for the replying me.

Hi Afzaal
As i hve clearly mentioned in my first post do post the necessary details since the static route or the limited info provided by you in your posts takes nowhere..

Afzaalq007,
I'm making some rather large assumptions because you haven't provided the detail.
I think you've made a mistake in Router B It's addressing doesn't follow what you have in A and C. It looks like you are using 192.168.11.0/27 in RTR A
192.168.11.0/27 in RTR B and 192.168.11.64/27 in RTR C
My guess at why it works when you take A-B away is that the whole 192.168.11.0/24 is routed via RTR C anyway and RTR-C has the /27 routes that you are looking for anyway.
When the link between A-C goes away C trys to use B as per weighted route, RTR-B for it's part sends the packet onto RTR-A. RTR-A deals with it appropriately. It's the return path thats faulty. RTR-A dutifully sends the packet to RTR-B, RTR-B however only has two routes to 192.168.11.0/24 to RTR-A and 192.168.11.32/27 connected.
As I stated this is speculation as you haven't provided people very much to go on. If any of the above is correct the problem may be solved with a simple command at RTR-B such as
Ip route 192.168.11.64 255.255.255.224 s1
hope this helps

Hi
Can you apply this and check ?
Router A:
ip route 192.168.11.32 255.255.255.224 S0/0:0
ip route 192.168.11.32 255.255.255.224 S0/1:1 10
ip route 192.168.11.64 255.255.255.224 S0/1:1
ip route 192.168.11.64 255.255.255.224 S0/0:0 10
Router B :
ip route 192.168.11.0 255.255.255.224 S0/0:0
ip route 192.168.11.0 255.255.255.224 S0/1:1 10
ip route 192.168.11.64 255.255.255.224 S0/1:1
ip route 192.168.11.64 255.255.255.224 S0/0:0 10
Router C:
ip route 192.168.11.0 255.255.255.224 S0/0:0
ip route 192.168.11.0 255.255.255.224 S0/1:1 10
ip route 192.168.11.32 255.255.255.224 S0/1:1
ip route 192.168.11.32 255.255.255.224 S0/0:0 10

Hi,
I have same configuration just like you have pasted above, still probelem is same.
i have mention earlier.
thanks for the Annwer.

Afzaalq007,
Sorry I can't read the file my version of Visio isn't new enough. Spremkumars suggested config should work.
Can you post the output of a show ip route command from router B?
Can router B's ethernet interface 192.168.11.32/27 reach router C's ethernet interface 192.168.11.64/27 ?
What path does it take to do this? extended pings and trace commands required to do this..
What about during a failure of A-C WAN link?
A quick design question while I'm going. Is there a reason not to use a routing protocol?
Thanks
Tony
