From: dean <dlug...@gmail.com>
This last patch updates the function in OSPF that handles routing
table update notifications to use source information. Similar changes
are applied to the function that synchronizes OSPF routing tables with
nest's routing tables.
Finally, some work of area border routers (like deciding whether to
flush or originate summary LSAs) is also changed to support SADR
entries if SADR is enabled.
