Description

Configuring an IPv6 CARP VIP with a link local sync peer address does not appear to function properly. I've tried with and without a scope added to the address and in either case it does not appear to communicate with the peer. I made sure both peers were using the LL address of the other peer, but both claim MASTER status. If I change the peer to a non-LL address it works immediately.

Users can use non-LL sync peer addresses as a workaround, even if the VIP itself is LL.

If this is expected or not a valid use case, if that is the case we can document it as such.
