DES-7200 Configuration Guide Chapter 2 Configuring BGP IP VPN
2-70
Note
This command is only applicable to OSPF instance associated with VRF.
VRF OSPF instance can be configured with multiple domain IDs, but
there is only one primary domain ID. Others are secondary domain IDs.
The only primary domain ID is configured with "domain-id value"
command, while multiple secondary domain IDs are configured with
"domain-id value secondary" command. OSPF routes are advertised
when converted to VPN routes, and VPN routes only contain the primary
domain ID.
Different VRF OSPF instances can have the same domain ID. However,
VRF OSPF instances in the same VPN must be configured with the
same domain ID in order to guarantee the correctness of route
advertisement.
# Configure the primary domain ID and secondary domain ID of VRF OSPF protocol to
4.4.4.4 and 5.5.5.5 respectively.
