Syntax Description


`area-identifier`	Specifies the OSPF target area.
`policy-map`	Specifies a policy.
none	Specifies not to apply an external filter (removes the existing policy, if any).

Default

N/A.

Usage Guidelines

For switches configured to support multiple OSPF areas (an ABR function), a policy can be applied to an OSPF area that filters a set of OSPF external routes from being advertised into that area.

Using the none mode specifies that no external filter is applied.

The following command configures an external filter policy, nosales:

configure ospf area 1.2.3.4 external-filter nosales
