Description

Problem: When the LAN interface experiences a link down/up event. The IPv6 prefix assigned to the interface is lost. Only recovery is a system reboot (that I have found).

Details:

WAN: DHCPv6 Prefix Delegation size = /60
LAN (re0): IPv6 Prefix ID = 0

You can see the problem occurring in the routing.log

Note: The /60 does work. I have other OPT interfaces that get their prefix. Unique Prefix ID on each.

Have not tested to see if this problem occurs when the WAN prefix request is a /64.

Steps to reproduce:

1) Just bounce the LAN interface.
