Can I do what a "Fat Pipe" appliance does with only 2800 routers?

Hi,


I currently have 2 WAN links, a 20MB Ethernet BGP MPLS and a bonded T1.    I have a  2800 at each end configured to automatically fail over to the T1 in the event that the MPLS goes gown.  I put a high AD on the T1 connection with static routes.  If the MPLS goes down the T1 does kick in, however users are dropped from their applications and VOIP calls are disconnected.


I was looking into Fat Pipe appliances and they supposidly will fail over a connection without any packet loss - therefore not dropping a VOIP call or kicking anyone off the database application. In addition they will provide aggregated bandwidth.


Is there any way to achieve a similar failover without packet loss with just the routers?  Do I really need to purchase the Fat Pipe to achieve this?  Are there any alternatives?


Thanks.

Hi,


Before you purchase the "Fat Pipe" appliance, you may want to talk to your ISP and and use a routing protocol (BGP) to peer with them and test it to see if you get better results.
