I had my two T1/s went down in the same time/minute/sec this morning, they came back up in exactly 25 minutes. I am attaching the output of sh int sx/x/x.
I see a lot of resets on these interface.
Considering the attachment what could be the reason for this downtime? We didnt have any power problem diring the down time. Can a wrong OSPF config bring the lines down??
Forgot to mention, this is 2800 series router. Every T1 is from different ISP so I can not consider the ISP/s as a reason.
