Step
4. Redistribute remote site routes
advertised by the PE.
5. Configure the default cost
value for the redistributed
routes.
Configuring OSPF between MCE and VPN site
An OSPF process belongs to the public network or a single VPN instance. If you create an OSPF process
without binding it to a VPN instance, the process belongs to the public network.
By configuring OSPF process-to-VPN instance bindings on a MCE, you allow routes of different VPNs to
be exchanged between the MCE and the sites through different OSPF processes, ensuring the separation
and security of VPN routes.
An OSPF process can belong to only one VPN instance, but one VPN instance can use multiple OSPF
processes to advertise the VPN routes.
An OSPF process that is bound with a VPN instance does not use the public network router ID configured
in system view. Therefore, you must configure a router ID when starting the OSPF process. All OSPF
processes for the same VPN must be configured with the same OSPF domain ID to ensure correct route
advertisement.
For more information about OSPF, see Layer 3—IP Routing Configuration Guide.
To configure OSPF between MCE and VPN site:
Step
1. Enter system view.
2. Create an OSPF process for a
VPN instance and enter OSPF
view.
3. Configure the OSPF domain
ID.
4. Configure the type codes of
OSPF extended community
attributes.

By default, no route is redistributed
into RIP.
Optional.
0 by default.
Remarks
N/A
Perform this configuration on the
MCE. On a VPN site, create a
normal OSPF process.
Optional.
0 by default.
Perform this configuration on the
MCE. On a VPN site, perform the
common OSPF configuration.
Optional.
The defaults are as follows:
•
0x0005 for Domain ID.
•
0x0107 for Router ID.
•
0x0306 for Route Type.
