Hi,
I have the following output
router#sh ip route 167.175.107.0
Routing entry for 167.175.107.0/24

I dont want that packects take this route 200.1.147.121, from 200.1.147.121 as a second option but I want that packets balance using the other 3 routes.
The route 200.1.147.121, from 200.1.147.121 is not a diect route it is why I would like to have this route as a backup route. (last option)
What can I do to achieve this task?
Thanks

HI,
Simply you can influence this by increasing the bandwidth / delay on this PVC.
To prevent interference with Qos and other routing protocols, keep it simple and increase the delay to get this path out of best paths
R1(config-subif)#do sh int atm1/0.1 | inc DLY
MTU 4470 bytes, BW 149760 Kbit,DLY 80 usec,
R1(config-if)#int atm1/0.1 point-to-point
R1(config-subif)#delay 1000
R1(config-subif)#do sh int atm1/0.1 | inc DLY
MTU 4470 bytes, BW 149760 Kbit, DLY 10000 usec,
Please rate helpful posts.

Hi Mounir, I have a question Should I modify the delay in the atm interface of both routers (Site A & Site B)or only in the interface atm of one router (Site A)
Thanks

Hi,
Yes From both sides.
changing the delay from one side will increase the metric value of the advertised routes on the receiving side.
Example:
R1 EIGRP neighbor with R2, R1 advertise 100.10.10.0/24 if you changed the delay on R1 serial interface the metric of 100.10.10.0/24 on R2 will be increase, so to make sure your routing symmetrical increase the delay on both sides.
