The distribution of routes learned dynamically from the Border Gateway Protocol is configured under BGP.
- OSPF instance
- Contains the name of the OSPF instance.
- BGP instance
- Contains the name of the BGP instance.
- Prefix filter
- Name of the prefix-filter list from Prefix lists.
- Default action
-
Defines the default handling of prefixes that are configured in the prefix list. Possible values:
- Accept
- Deny
- Metric source
- Specifies which source is used to set the OSPF metric.Possible values:
- Constant
- A user-defined constant metric is used.
- Protocol
- The "Local preference" value of the BGP prefix is used or imported.
- Constant metric
- If the metric source is set to "Constant", the OSPF metric of the imported routes is set to the value Constant metric.
- Path type
- Specifies the type assigned to the routes imported into OSPF.Possible values:
- External type 1
- The OSPF metric is formed from the redistribution metric or constant metric + the total path metric used to reach this ASBR.Note: In the OSPF routing algorithm of routers, type 1 routes are generally preferred over type 2 routes.
- External type 2
- The OSPF metric is formed from the redistribution metric and/or the constant metric.
- External route tag
- Specifies which external route tag the routes are imported with.Note: The value is not processed by OSPF itself.
