In my 7200 router one of the Gig interface is going down in every 30 minutes. The physical interface is not going down, and I dont have any log for that. But my ospf neighbourship is resetting in every 30 minutes and I am losing my pinging at the same time. The problem started after I changed my router last week.
I am using 7200 series router with ios Version 12.4(3i) . I have configured the ip in the subinterface . Please advise
