I have configure a GRE tunnel between two routers A & B, such that on Router A:
I am using fastethernet interface.
On router B I am using vlan 1 interface, as HWIC4ESW card is installed in this router.
I am able to ping GRE tunnel end to end but OSPF adjency is not developing on this link. Can anyone please advise? Is there any issue like with vlan interface OSPF adjency can't be developed. Thanks.
