[alsayed]

HI!

I need to configure 2 routers(each one BACK up to each others)for WAN Connection & FOR gateway redanduncy.the connection is 2 radio link to the HO.I NEED To implement a redundancy link if one fail the other will takes over.also i need HSRP IN MY NETWORK.HOW CAN I ACHIVE THAT?CONFIGURATION IT WILL VERY MUCH APPRECIATED

10XS FOR UR HELP

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.

Hi Ali,

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 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.

HI Ankur

do i connect the 2 routers to each distribution switch.each router has 2 fiber connection to each distribution switch for redandancy?this is correct Ankur

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.
