Re: BGP Synchronization - When do OSPF and BGP router ID need

With synchronization enabled, The router needs to learn of a route via an
IGP as well as BGP.

In addition, with OSPF only the ID of the router originating the route in to
OSPF and the ID of the router originating the route in to BGP must also
match.
