Command Remarks
7. (Optional.) Configure OSPF
to redistribute the default
route.
default-route-advertise summary
cost cost
By default, OSPF does not
redistribute the default route.
This command redistributes the
default route in a Type-3 LSA. The
MCE advertises the default route to
the site.
8. Create an OSPF area and
enter OSPF area view.
area area-id
By default, no OSPF area is
created.
9. Enable OSPF on the interface
attached to the specified
network in the area.
network ip-address wildcard-mask
By default, an interface does not
run OSPF.
Configuring IS-IS between an MCE and a VPN site
An IS-IS process belongs to the public network or a single VPN instance. If you create an IS-IS process
without binding it to a VPN instance, the process belongs to the public network.
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.
To configure IS-IS between an MCE and a VPN site:

Command Remarks
1. Enter system view.
system-view N/A
2. Create an IS-IS process for a
VPN instance and enter IS-IS
view.
isis [ process-id ] vpn-instance
vpn-instance-name
Perform this configuration on the
MCE. On the VPN site, configure a
normal IS-IS process.
3. Configure a network entity
title.
network-entity net By default, no NET is configured.
4. (Optional.) Redistribute
remote site routes advertised
by the PE.
import-route protocol [ process-id
| all-processes | allow-ibgp ] [ cost
cost | cost-type { external |
internal } | [ level-1 | level-1-2 |
level-2 ] | route-policy
route-policy-name | tag tag ] *
By default, IS-IS does not
redistribute routes of 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.
5. Return to system view.

6. Enter interface view.

7. Enable the IS-IS process on
the interface.
isis enable [ process-id ] By default, IS-IS is disabled.
Configuring EBGP between an MCE and a VPN site
To run EBGP between an MCE and VPN sites, you must configure a BGP peer for each VPN instance on
the MCE, and redistribute the IGP routes of each VPN instance on the VPN sites.
Routes redistributed from OSPF to BGP on the MCE do not carry OSPF attributes. To enable BGP to
distinguish routes redistributed from different OSPF domains, you must enable the redistributed routes to
