Router Failover

[chazk1]

I have 2 Routers on the same network.

I PING a server the other side of the WAN from my PC and get the desired response.

When Router 1 is powered off, no ip traffic can access the WAN via Router 2. My PING session advises 'Response Timed Out'. When Router 1 is powered on the WAN is accessible.

Anyone know why ? Misconfiguration on one or both Routers ?

 

[bobthecat]

Are you using HSRP ? I hope this was of help to you XXX

 

[bobthecat]

If your routers are not using HSRP and your default gateway is router 1, when you switch it off I would expect you ping to timeout. I hope this was of help to you XXX

Sorry for the "I hope this was of help to you XXX" message. I came in drunk one night and I was messing around and forgot about it ................ Bob ^^

 

[jeter]

on the 2nd router how is it setup? HSRP as asked by bobthecat. Do you have some sort of routing applied?

Hi,

HSRP was enabled recently but problem highlighted itself prior to adding to config. IP clients could not access server across the WAN via Router 2 when Router 1 failed, Decnet clients appeared ok. Both Router configs below:

There is a lot of info in your configs that I do not understand but I have a few ideas.
1) I think HSRP is ok, although I don't think you use preemt on the lower priority interface.
2) To check your HSRP type "Show standby" on router1, this will show you the local state and standby router info.
3) If router1 is down do a trace route from your PC to see how far it gets.
4)The static routes in router1 config are not present in router2, is this just a cut&paste error?

BTC,

Correct re: point 4, was a C&P error.
Will check other options.

Thanks
