Static address + RA working on FreeBSD and Linux. Sorry we don't have
other servers, where we are using statically configured IPv6 addresses.

Define for every application your bind address - locally generated packets
will use it. If it is not possible Use RFC 3484 source address selection
for selecting static source addresses.

Statically configured default gateways worked for us with VRRP/HSRP.
VRRP/HSRP is for first-hop redundancy.
