Hi, all.

I've been testing OSPF functions.

All of them are working normally except one thing.

I shutdown all interfaces of one node with "ifdown intf" command after zebra 
and ospfd startups.

(I tested this experiment on 4*4 2d Torus network.)

Of course, I found that a new detour path was created.

And I executed "ifup intf" command to check if the original path(it's the 
shortest path) would be recovered.

But the original path was recovered even though I started zebra and ospfd 
daemon after killing them.

Only one case, system rebooting, was successful.

One expert recommended that I try to modify the code

because the OSPF v2 standard doesn't include path recovery about my case.


But the quagga code was very complicated and I cannot solve the problem in a 
short time.

This is the reason why I' asking your help.


Thank you in advance.



Best regards,

Jeongsook.
