| reply to wasiim You've got two problems that requires getting "one" worked out before proceeding, ideally, getting failover (VRRP) to work first.
The reason your VRRP failover configuration may not have worked is because you most likely did not set the priority level on the first concentrator. As a side note, in the CCNP curriculum, configuring VRRP is based on routers, so that's the only frame of reference I have, so bear with me 
By default, both routers have a priority of 100. If this happens after vrrp is enabled on both routers, then the router that has the higher ip address becomes the master. So, to counter this, you have to increase the priority on the router (or concentrator in your case) you want to be the master.
On a router interface, you'd enter this command at the global config: vrrp 1 priority 150
Because I've yet to work on a concentrator, I could't really advise you on that, but this is how you'd do it on an IOS router.
Truthfully, it may be more worth your time to post this question in the Cisco forum; look for Rolande, Aryoba, MSN, or TomS (to name a few) to respond with assistance.
