Usage guidelines
After you configure a domain ID for an OSPF process by using the domain-id command, when you
redistribute OSPF routes into BGP, BGP adds the configured OSPF domain ID to the redistributed BGP
VPN routes as a BGP extended community attribute and advertises the routes to the BGP peer. When you
redistribute the BGP VPN routes into OSPF on the BGP peer, OSPF uses the domain ID to determine
whether the routes belong to the same OSPF routing domain. If yes and the routes are intra-area routes,
OSPF advertises these routes in Summary LSAs (Type 3). If yes but the routes are not intra-area routes,
OSPF advertises these routes in AS External LSAs (Type 5) or NSSA External LSAs (Type 7). If not, OSPF
advertises these routes in Type 5 or Type 7 LSAs.
