Description (partial)

Symptom:
Local LAN-only prefix present in master route-import table but not present in site prefix DB

After a routing problem on the overlay, a prefix may be learned on both the LAN and WAN interface of a PFRv3 border router. In some situations it is possible that after clearing the routing loop, the affected prefixes are missing in the site prefix table of the router that should be originating them into the IWAN domain. During this time, the prefixes are present in the route-import table but they are missing in the site-prefix table.

Conditions:
The prefix is not advertised to other IWAN sites.
