Usage guidelines
When you redistribute OSPF routes into BGP on the MCE, 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 Type-3 LSAs; if yes but the routes are not intra-area
routes, OSPF advertises these routes in Type-5 or Type-7 LSAs. If not, OSPF advertises these routes in
Type-5 or Type-7 LSAs.
With no parameter specified, the undo domain-id command deletes all domain IDs.
