To do...
Configure the default values of the
parameters for the redistributed
routes, including the route cost,
count limit, tag, and type
Configure the type codes of OSPF
extended community attributes
An OSPF process that is bound with a VPN instance does not use the public network router ID
configured in system view. Therefore, you need to 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.
An OSPF process can belong to only one VPN instance, but one VPN instance can use multiple
OSPF processes to advertise the VPN routes.
After you configure an OSPF instance, you need to enable OSPF. The configuration procedure is
the same as the common OSPF configuration. For OSPF configuration details, see OSPF
Configuration in the Layer 3 - IP Routing Configuration Guide.
Configuring route exchange when using IS-IS
An IS-IS process can belong to only one VPN instance. If you do not bind an IS-IS process with a VPN
instance, the process will be a public network process.
Follow these steps to configure route exchange when using IS-IS:
To do...
Enter system view
Use the command...
default { cost cost | limit limit | tag
tag | type type } *
ext-community-type { domain-id
type-code1 | router-id type-code2
| route-type type-code3 }
Use the command...
