friends!! Iam facing a problem in a ISP environment. Customers connect to our isdn router(3640) and static ip was given to diff customers and these static ips are redistributed in to ospf and they can brouse very well and it is fine.But the problem is ..suddenly sometimes they can't browse the net when he reconnects the net and datatranfer becomes zero. When i clear ospf redistribution ,it works ..but i have to do this atleast 5 times a day. Can anybody pls tell me what's the reason?? Why static ip is not getting redistributed in to ospf when customer connects again?? I tried changing IOS version..but no use... Presently iam running 12.0... Hope somebody will throw some light on this ravi __________________________________________________ Do You Yahoo!? Yahoo! Shopping - Thousands of Stores.
