10XS FOR UR HELP

Hi Ali,
Yes you are right. How will you take the 2 fiber connection from each router? You will be having one single ethernet on which you are running HSRP right?
I think your setup should look like this
router1 router2
| |
| |
access layer switch
| |
| |
1 dist switch 2 dist switch
or else
connect each router with dist switch with single cable and then connect your distribution switch together that will also take care of the design.
HTH, if yes please rate the post.

Hi Ali,
You can implement HSRP on your lan interfaces to have redundant as well as load balancing and you can implement interface tracking for your wan interfaces so that if any of the wan interfaces goes down it can be tracked and active router will reduce its priority and standby router will take the role.
Have a look at this link which will give you complete idea of HSRP implementation with interface tracking option

Hi Ali,
Have a look at the sameple config for one router
Router A
interface ethernet 0
ip address 1.0.0.2 255.0 0.0
standby 1 ip 1.0.0.4
standby 1 preempt
standby 1 priority 105
standby track serial 0
!
interface serial 0
ip address 3.0.0.1 255.0.0.0
Now this way serial 0 will be tracked by ethernet0 interface and incase serial goes down the priority of ethernet0 which is configured as 105 will be reduced by 10 by default so it will result in priority as 95 which will be less than priority configured on the other router which may be cofigured as 100 so the other router will become active for all traffic.
Also please have a look at the link which I posted in my previous post and click on the option for interface tracking it will give you a topology view as well as sample config also.
HTH, if yes please rate the post.

Hi Ali,

standby 1 ip 1.0.0.4
standby 1 preempt
standby 1 priority 105

!
interface serial 0
ip address x.x.x.x x.x.x.x
Router B
interface ethernet 0
ip address 1.0.0.3 255.0 0.0
standby 1 ip 1.0.0.4
standby 1 preempt
standby 1 priority 100
!
interface serial 0
ip address x.x.x.x x.x.x.x
Hi Ali..do not take me wrong but try to understand the concept and do not rely on the configurations posted. If you understand the concept you will be able to build to config on your own.
