Parameters
domain-id: OSPF domain ID, in one of these formats:
• Integer, in the range of 0 to 4294967295. For example, 1.
• Dotted decimal notation. For example, 0.0.0.1.
• Dotted decimal notation: 16-bit user-defined number in the range of 0 to 65535. For example,
0.0.0.1:512.
secondary: Specifies a secondary domain ID. Without this keyword, the command specifies a primary
domain ID.
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 as the local site. If the routes
are intra-area or inter-area routes in the same OSPF routing domain, OSPF advertises these routes in
Summary LSAs (Type 3). If the routes are not intra-area or inter-area routes but they belong to the same
OSPF routing domain, 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 AS
External LSAs (Type 5) or NSSA External LSAs (Type 7).
With no parameter specified, the undo domain-id command deletes all domain IDs.
