HSRP problems with OSPF

fgeryl

hello all,

I have an architecture problem. Here is my network

architecture:

/---------------Router B---------------\

Router A LAN

\---------------Router C---------------/

On the LAN side, HSRP is configured (Router C is

active). OSPF is used as routing protocol on each

router.

If Router C fails, HSRP works well and packets pass

through router B after 10 seconds. But when Router C

comes up again, HSRP immediately (in 10 seconds)

redirects packets on Router C but OSPF routing table of Router C isn't effective before 1 minute so during 1 minute every packets are dropped. What can I do to avoid this problem?

Thanks for your help.

You can use the "standby preempt delay 60" directive to keep HSRP from immediately failing back to the primary router.
