dhcpv6 failover issue

[Glenn Satchell]

Failover peers must be used inside a pool. This is the way it is meant to
work:

  subnet6 2001:4408:5205:128::/64 {
    pool {
      range6 2001:4408:5205:128::01 2001:4408:5205:128::FF;
      failover peer "fo";
    }
  }

Shared network is not mandatory.

If this doesn't work then it's a bug and should be logged.
