Hi Experts,

I saw this paragraph in Implementing IPv6 networks by Regis Desmeules.

"It is not recommended in the IPv6 specifications to use an
aggregatable
global unicast or site-local address as a next-hop
address. If you do,
Internet Control Message Protocol for IPv6 (ICMPv6)
redirection messages (Type
137) will not work. The next-hop address has
to be a link-local address.
However, when you configure a link-local
address as the next hop, you must
identify in the configuration the
corresponding network interface on the
router. In the Cisco IOS
Software technology, the recommended syntax for the
ipv6 route command
in this situation is ipv6 route ipv6-prefix/prefix-length
interface
link-local-address."

What is it that causes the redirect messages not to work when a global
unicast or a site local address is used as a next-hop address.

Thanks,

Surendra
