Syntax Description

area-identifier Specifies the OSPF target area.

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.

configure ospf area external-filter nosales
