Do you want both links to be active and in use at the same time, or active/standby?

HI,

          I want active & active ...

Thanks

Muthukumar

Hi,

 I need ISP link is active & active and router is Active & standby..

Thanks

Muthukumar

HI,

          Please help on this..

Thanks

Muthukumar

Hi

Could you not just use GLBP as its active/active by default or else split the subnets have multiple groups to make active/active in HSRP or VRRP , its a active/standby protocol so its not really suited for active/active

Hi ,

       Can i get the GLBP configuration for this ?and can you confirm that  whether GLBP supported for  cisco 2911 router..

Thanks

Muthukumar

yes its supported , just change the vrrp to glbp

Hi,

   I am understanding that GLBP for Router HA right..Can i get link load balancing for ISP Link and pls suggest, whether both isp link terminated to single router or separate router..

Thanks

Muthukumar

Hi

If your using BGP you need to look at single/multi BGP  homing load sharing you can manipulate the metrics to chose what to be learnt etc from each ISP as primary/secondary paths

Hello Muthukumar,

So you have 2 routers connected to your provider. Also there are 4 interfaces on this device configured for VRRP group 1, this might cause conflict as the VIP address will have 4 differents IP addresses, such a thing is not possible.

How these interfaces are connected to the other router? Maybe you can either define more than one VRRP group.

-Max

Hi Max,

                 Earlier i have tried with 4 vrrp group means each interface is having each group even also ISP Link is flapping when both routers are in live..

Thanks

Muthukumar
