Hello,
our insitution uses link-local prefixes for IPv6 point-to-point links
(like fe80::1/64 on one side, and fe80::2/64 on another one).
I want to have one such address to shared via heartbeat/resource-agents
between two physical routers.
Apparently, current code refuses to add a shared IPv6 address if it
is in a link-local scope. The following patch tries to be less strict.
Link-local scopes are allowed now, provided that they are accompanied
with the name of the interface.
Please consider applying the following patch:

Please don't top post and in particular don't attach entire digests to your
