So my question is then is that if cost is set to 0xffff, then at that value, virtual link should still work ! Or am I missing something here ? Thanks for the post Brian,

After reading ur article , now i realize i configured the aut-cost reference-bandwidth previously. But in my case i don't have any interface with maximum cost, because i can ping the loopback interfaces of both routers from both routers and both routers only had one path to reach each other! Please clarify if i misunderstood ur article ! Thanks again for this information! Atleast , now i know that there was some technical mistake done by me at that time which is kind-a-relief!
