Usage guidelines
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 they do and they are
intra-area routes, OSPF advertises these routes in Summary LSAs (Type 3). If they do but they are not
intra-area routes, OSPF advertises these routes in AS External LSAs (Type 5) or NSSA External LSAs (Type
7). If the routes do not belong to the same OSPF routing domain, OSPF advertises them in Type 5 or Type
7 LSAs.
With no parameter specified, the undo domain-id command deletes all domain IDs.
