IPv6 addresses.

                   Hi All,

For IPv6 testing we configured loopback addresses with prefix starting with 2002.Necessary routing was configured as per requirement.But

unfortunately we were not able to ping the loopback ip address from remote subnet.When it was being pinged from remote subnet the error

that was "General Failure/Ping transmit failed ".To the best of my knowledge this error comes when there is a issue in the LAN card connectivity.

But the PC was able to ping Default gateway.

Can someone help me out with this.

2002::/16 prefixes are reserved for 6to4 tunneling, and most clients will be sending protocol 41 encapsulated packets to the anycast gateway address 192.88.99.1/24, probably not where you expected.  Try a different prefix, such as 2001:db8::/32 (documentation, not globally routable) or something with a uniqule local address prefix under fd00::/7.
