You can configure a redistribute entry for OSPF to announce routes of a certain source type, for example, static, RIP, or direct. If a route policy field is not configured for a redistribute entry, then the default action is taken on the basis of metric, metric-type, and subnet configured. This is called basic redistribution. Otherwise, you use the route policy specified to perform detailed redistribution. If no redistribution entry is configured, no external LSA is generated for non-OSPF routes.
You can also configure OSPF redistribute policies in the OSPF redistribute tab of the Policy dialog box. See Configuring an OSPF redistribute policy.
Note:
Changing OSPF Redistribute contexts is a process-oriented operation that can affect system performance and network reachability while performing the procedures. Therefore, Nortel Networks recommends that if you want to change default preferences for an OSPF Redistribute context, you should do so before enabling the protocols.
To set up or edit an OSPF redistribute policy:
| The OSPF dialog box opens with the General tab displayed. |
| The Redistribute tab opens. |
| The Policy, Insert OSPF Redistribute dialog box opens. |
