Need Help in Configuring Router for Redundant Link

[utawakevou]

Hi,

Just need help in configuring a redundant test link. We got another telco who is proposing and they have given us a month to test their solution. Got a 2800 rotuer at my HQ and an 1841 router at the remote office.Am planning to use  the fastethernet 0/1 on the 2 routers for the test link and route traffic to that test link for the whole month to test.

Currently im running static routes going through the serial interface using a different telco lease circuit and would really apprcaite any help in configuring either static or dynamic routing to have both links running however use the test link as the primary and the current link as the failover link. Am thinking of using OSPF for dynamic routing. Refer to the diagram attacch for the setup. Any help, tips, configuration example will be really appreciated

You can use static route.  If you want the new circuit to be the primary then you use the default admin distance of 1

Then for the other link that you want to use for backup only, use the same static route with higher admin distance

Example:

ip route 10.10.10.0 255.255.255.0 182.168.1.1 10 (primary circuit)

ip route 10.10.10.0 255.255.255.0 182.168.1.1 10 50 (backup circuit)

Thanks Reza. So in my case, since at the remote site there is only a default route then Iwill just add another one but pointing to the test link addin the admin distance of 1 ? At the HQ, got 3 static routes that will need to be added but pointing to the test link with admin distance of 1 ?

Correct, for the primary site you don't need to type the admin distance, because that is default. For other link you give it a number higher then 1.

On the "lighter" side of things, what is the link speed?

Both link will be running 2mbps. Current running on telco lease circuit- cable while the test will be on the licensed wireless link
