Hi Guys,
I have a problem where I have 3845 router and c3845-advsecurityk9-mz.124-24.T5.bin dis is the IOS running on it and there's a back up BRI interface for the serial. Now if my serial link goes it normally goes to my BRI, once we had a time where the BRI was also down and when we restored back the Serial link we were still not able to reach the other side. We are using OSPF routing to reach the destination. When this happens and when we reboot this router we are able to reach the destination. sometimes we are able to reach it when we remove ospf and use static and now if we put back the ospf routing the link comes back, this happens again and again, need urgent help on this, any advice would be helpful.
Regards
Krishna
