i know that manipulating the BGP convergence it may increase TCP traffic and consequently increase CPU load but i m not geeting specific routes from ISP, i m just getting 1 default route from both the ISPs.
This command is useful if you are learning your BGP peer address via an IGP which is not the case here. I assume your eBGP session are built on the interface IP addresses.
I don't think you have a convergence issue on your side because as soon as the link failed, the router will install its backup route. The 1mn is the time for the internet to converge for the returning traffic and I don't think there is something you can do.
If you're using eBGP, the convergence times don't work like normal holddown timers for an IGP. Once your provider sees the link in a down/down state, it will automatically failover to the other router. It will still keep trying to contact the primary router until it completely times out, but your backup router will be used. You don't have to mess with timers to get this to work.
I ran into this problem with our ISP because I didn't want it to failover so quick, but I soon learned that it wasn't something I could control.
