Backup route question

Unanswered Question
Apr 16th, 2007

Hi All,


trust you all are well. Its been a while ...:)


I'm busy moving clients from one router to another. They are all on E1's on and currently on a C3640 router. This router also has the ISDN backup infrastructure on it.....ie.... should the client connection to us drop, it dials up via ISDN backup to this router. In other words every serial interface has a backup configured to a dialer interface.


Now....


I have configured the clients on a NEW router - c7206. I'm ready to do the cutover BUT I am worried about the backup routes.


How would I conf the 7200 with a floating static to the dialers configured on the 3640?


Hope this all makes sense.


Thanks

Brad,


You can use floating static routes to achieve this.

Connect the 3640 router to the 7206.

Add a primary route on the 7206 pointing to the E1.

Add a floating static route with a higher AD pointing to the 3640.


WHen the link fails, the 7206 would sense this and start forwarding the traffic towards the 3640 where it will match the dialer list and dial out


HTH, rate if it does

What would the route statement be on the 7200 then?


ip route 250


Would this be how I would impliment it and the existing routing on the 3640 to the dialer interfaces created?

the next hop should be the interface IP which will be connecting to the 3640

So basically my route statement should read something like ...


ip route 172.40.0.0 255.255.0.0


The 3600 in turn would then know what to do with this route as I have the route below on it as a backup


ip route 172.40.0.0 255.255.0.0 Dialer2 240 name
