influencing eigrp path over tunnel interfaces

[carl_townshend]

Hi all

If I have 2 routers using hsrp, each router has a tunnel to the remote site over its WAN connection, How can you influence the path eigrp takes over a tunnel? ie which tunnel to choose cause surely they would be the same AD to reach?

cheers

How about by setting different delay values on the two tunnels?

[Giuseppe Larosa · Accepted solution]

Hello Carl,

you can change delay on the tunnel interface as EIGRP metric is cumulative in delay

interface tunnel x

delay  Y

where delay is expressed in tens of microseconds

you can check current settings of delay with

show interface tunnel x

You should increase delay from default value on the tunnel you don't want to use.

However, you should consider if it is not better to leave each router to use its own tunnel to reach the remote site as it happens now.

Hope to help

Hello Giuseppe,

I have done the same in my branch routers (two of them), but this is not reflecting in routing table at HO side. is there anything else that i need to do after changing delay? like clearing relationship or something else.

I labbed this up in GNS3 and it worked without any clearing of neighbors.

I am stuck now.. :-(

thanks in advance,
