Parameter

Parameter

Description

vrf <vrf-name>

Optional. Specifies a VRF name. The value is a string. It’s a user-defined VRF set by the command set ip vrf <vrf-name> [description <string>].

If no VRF is specified, export the route in default VRF.

export <policy-name>

Specifies the policy name. The value is a string.



Usage Guidelines

OSPF export filters act upon routes just before they are to be advertised by OSPF routing protocol.

OSPF export consists of two types of applications:

  1. The OSPF route advertised to neighbors is filtered and modified by configuring routing policy.
  2. Introducing route learned from other routing protocols (could be BGP, RIP or static routing) from routing table into OSPF by configuring the routing policy with this command:

set policy policy-statement <policy-name> term <term-name> from protocol <bgp | connected | ospf4 | ospf6 | rip | static>



Example
• Configure OSPF export a routing policy to implement the introduction of static route into OSPF route.
