How Improve Re-Convergence Times?

Unanswered Question
Feb 5th, 2009

I am measuring re-convergence times between LAN routers of between 1-5 seconds. Can the router settings be tweeked to improve that time?

Configuration is:

2 routers in cluster configuration on west side (R1, R2) to provide redundant links.

1 router on east side.(R3)

2 links connecting east to west (1 link prioritized so its primary).

2nd link is a failover link in case primary goes down.

Links configured for OSPF.

R1 \

| R3

R2 / (Lines represent the links)

When I pull Primary link to R3, it takes 1-5 seconds for link to re-establish the link on the secondary side.

Any thoughts appreciated.

Thank you!

Are R1& R2 running HSRP and tracking the links status to R3?
