Usage guidelines
router-id
router-id
An OSPF process that is bound to a VPN instance does not use the
public network router ID configured in system view. Therefore, you must
specify a router ID when creating a process or configure an IP address
for a minimum of one interface in the VPN instance.
vpn-instance
vpn-instance-name
An OSPF process can belong to only one VPN instance.
If you delete a VPN instance, all OSPF processes of the VPN instance
are also deleted.

Enable OSPF on the interface attached to the specified network in the area.
network ip-address wildcard-mask
By default, an interface neither belongs to any area nor runs OSPF.
Configuring IS-IS between an MCE and a VPN site
About IS-IS between an MCE and a VPN site
Binding IS-IS processes to VPN instances can isolate routes of different VPNs. For more information
about IS-IS, see
Layer 3—IP Routing Configuration Guide
.
Perform this configuration on the MCE. On a VPN site, configure a common IS-IS process.
Procedure
1.
Enter system view.
system-view
2.
Create an IS-IS process for a VPN instance and enter IS-IS view.

An IS-IS process can belong to only one VPN instance.
3.
Configure a network entity title.
network-entity net
By default, no NET is configured.
4.
Create the IS-IS IPv4 unicast address family and enter its view.

By default, IS-IS does not redistribute routes from any other routing protocol.
If you do not specify the route level in the command, the command redistributes routes to the
level-2 routing table by default.
