EIGRP Query

[nidhin.chandran]

Hi all,

I have one router which running on EIGRP and having  two ISP link  which s connected to the same Router.

Is it possible to configure Redundancy(Active/stand by) on this Router ?.

Anyone please explain with sample Configuration.

Many Thanks,

Nidhin Chandran

On second link you can use a offset-list (in and out) to increase the metric and have only a preferred path through the first link

If you mean to have a primary path and a backup path, one through the first ISP and the other using the second ISP, then you have to tune the metric of routes you receive from the ISP's. May be the routes already has different costs, it depends on links bandwidth and delay and metric  in ISP routers. In any case you can tune their costs using delay or bandwidth command under interfaces. Usually it's better to use delay command.

Hello

If currenty you have eigrp equal paths to either ISP then the easiest way is introduce some interface delay on your preffered secondary path, this will provide you with the redundancy you require.

Your router

int x/x ( isp link ?)
Delay 10000
