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:

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.

Not advertised by default.
Tuning and optimizing OSPF networks
You can optimize your OSPF network in the following ways.
• Change OSPF packet timers to adjust the OSPF network convergence speed and network load. On
low speed links, you need to consider the delay time for sending LSAs.
• Change the SPF calculation interval to reduce resource consumption caused by frequent network
changes.
