Hi,
Thanks a lot for this quick response. Yeah, I am trying to do a ping on
the link local address.

The following is the configuration:

Machine A
---------
eth0: inet6 addr: fe80::2d0:b7ff:fe06:6ae5/10 Scope:Link

Machine B
---------
eth0: inet6 addr: fe80::2e0:29ff:fe24:9b23/10 Scope:Link
eth1: inet6 addr: fe80::2e0:29ff:fe24:9b22/10 Scope:Link

Machine A and Machine B eth1 are in the same Ethernet link.

From Machine A, I am trying to ping Machine B eth1 as:

Machine A> ping6 -I eth0 fe80::2e0:29ff:fe24:9b22
bind icmp socket: Invalid argument
Machine A>

How to avoid this error? 

Thanks in advance
Siva

I suppose you're trying to ping6 to link-local address.
You need to specify link like this:
  % ping6 ff02::1%eth0
