OSPF networking convergence problem

Hello , 

I have a 60D with 2 active OSPF neighbors to 2 other routers . working in main & backup mode over L2 VPLS. If I shutdown the link to the router with the MAIN ospf neighbore , routing monitor on the 60D is updating to the Backup as it shuld. When returning the Main back to Active , routing monitor on the 60D is not updating and the traffic is steel sent to the backup. It never comes back to the main neighbore until I shut and no shut the backup link .

any Idea ?

Hello,

you should check (and may be share) the OSPF neighbors and OSPF routes in the different scenarios. 

active/backup

get router info ospf neighbor

get router info ospf route

get router info routing database

 

active (down)

get router info ospf status

get router info ospf neighbor

get router info ospf route

get router info routing database

get router info ospf database

 

active (up)

get router info ospf status

get router info ospf interface

get router info ospf neighbor

get router info ospf route

get router info ospf database

get router info routing database

 

Best regards,

Benoit

Welcome to the forums

 

Perhaps add a cost to the backup link so that it will be farther when the main comes back online.
