Hi All,

I have a very simple IPv6 question.

I have two routers connected back-to-back on a serial link.

router1 (serial3/1) ------------------------------------( serial0/0/0)
router2

But i am not able to ping the global unicast address from one side to
on the other.

I think its something elementary, but not able to figure out what ?.

Please help me to understand this.

Thanks,

Surendra
