Hello  ankitohc,

In ISP router you have configured two  different ospf processes ospf 2 and ospf 4....one is enough right...?

If you want to go with two process id's....we should configure redistribution between them... I think redistribution is missing in ISP router.

Best regards

@Gopinath_Pigili  Hello

I used the different OSPF process ID 4 .. I should have been used process ID 2 instead of 4 for 2.2.2.0 network.

After changing the process ID to 2 ..tunnel is up now..
