Export Route-Policy - HP FlexFabric 12500 Command Reference Manual

Usage guidelines
When you redistribute OSPF routes into BGP, BGP does the following:
Adds the configured OSPF domain ID to the redistributed BGP VPN routes as a BGP extended
•
community attribute.
• 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.
Examples
# Configure an OSPF domain ID.
<Sysname> system-view
[Sysname] ospf 100
[Sysname-ospf-100] domain-id 234
