Using the import-route command cannot redistribute a default external route. To do so, you need
to use the default-route-advertise command.
To configure OSPF to redistribute a default external route:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPF view.
ospf [ process-id | router-id router-id
| vpn-instance vpn-instance-name ] * N/A
3. Redistribute a default route.
default-route-advertise [ [ [ always |
permit-calculate-other ] | cost cost |
route-policy route-policy-name | type
type ] * | summary cost cost ]
Not redistributed by default.
NOTE:
The default-route-advertise summary cost command is applicable only to VPN, and the default route is
redistributed in a Type-3 LSA. The PE router will advertise the default route to the CE router.
3. Configure the default parameters for redistributed routes.
You can configure default parameters such as the cost, upper limit, tag and type for redistributed
routes. Tags indicate information related to protocols. For example, when redistributing BGP
routes, OSPF uses tags to identify AS IDs.
To configure the default parameters for redistributed routes:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPF view.
ospf [ process-id | router-id router-id
| vpn-instance vpn-instance-name ] * N/A
3. Configure the default
parameters for redistributed
routes (cost, route number, tag
and type).
default { cost cost | limit limit | tag
tag | type type } *
Optional.
The default cost is 1, the
default maximum number of
routes redistributed per time is
1000, the default tag is 1, and
default type of redistributed
routes is Type-2.
