EIGRP convergence time

Hi All

I hope someone can help i am trying to speed up the convergence time of EIGRP

basically we have two offices connected by a 10mb point to point using a primary router in each office and connected via ADSL and a VPN tunnel using a back up router in each office

also we run HSRP between the primary and backup routers in each office

if the 10mb lines goes down it fails over to the back up VPN but drops around 3 ping i have read that this can be sub second

the time seem to be when the London end is waiting for the eigrp dead timer to time out for its link to the primary router in Sheffield

once this has timed out the router via the 10mb link is dropped and it sends traffic by the back up router in London and then across the VPN to the back up router in Sheffield

the primary router in london does have a FS for sheffield to go via the backup link but only uses it once the primary route is dropped

any ideas?

thanks !

Ok, are EIGRP hellos sent to also the FS (back up router) aswell as the S?

thanks for so much input everyone!

will give it ago with a ping runing across the tunnel so that should keep it up

thanks

Ben

You should not need ping - just "keepalive 1 3" on the vti interface @ both ends.
