Step Command Remarks
3. (Optional.) Configure an
OSPF domain ID.
domain-id domain-id [ secondary ]
The default domain ID is 0.
Perform this configuration on the
PE.
The domain ID is carried in the
routes of the OSPF process. When
redistributing routes from the OSPF
process, BGP adds the domain ID
as an extended community
attribute into BGP routes.
An OSPF process can be
configured with only one domain
ID. Domain IDs of different OSPF
processes can be the same.
All OSPF processes of a VPN must
be configured with the same
domain ID.
4. Configure the type codes of
OSPF extended community
attributes.
ext-community-type { domain-id
type-code1 | router-id type-code2
| route-type type-code3 }
The defaults are as follows:
• 0x0005 for Domain ID.
• 0x0107 for Router ID.
• 0x0306 for Route Type.
Perform this configuration on the
PE.
5. Create an OSPF area and
enter area view.
area area-id
By default, no OSPF area is
created.
6. 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 a PE and a CE
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.
To configure IS-IS between a PE and a CE:
Step 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
PE. On the CE, configure common
IS-IS.
3. Configure a network entity
title for the IS-IS process.
network-entity net By default, no NET is configured.
4. Return to system view. quit N/A
5. Enter interface view.
interface interface-type
interface-number
N/A
6. Enable the IS-IS process on
the interface.
isis enable [ process-id ]
By default, no IS-IS process is
enabled on the interface.
