imported to OSPF at the remote end. To achieve this goal, we can configure a
Domain-id for each OSPF domain. A Domain-id is attached to a BGP/VPN route when
an OSPF route is imported into BGP/VPN for transmission over BGP/VPN routes.
Then when BGP routes are imported to the peer PE, LAS values are filled in according
to the extended community attributes. If the received BGP VPN IP routes have the
same Domain-id, they are from the same VPN instance route.
By default, Domain-id is 0.
Caution:
The specified Domain-id will not take effect until the reset ospf command is executed.
Example
# Set Domain-id 100 to OSPF process 100.
[Quidway-ospf-100] domain-id 100
[Quidway-ospf-100] domain-id 0.0.0.100
