Procedure

There are two steps for configuring OSPF import and export:

1. Configure the routing policy to detail the routing filter conditions and actions;
2. Use OSPF import a policy to filter OSPF routes added into RIB, or OSPF exporting a policy to filter routes advertised from RIB or introduce routes learned by other protocols into OSPF routing table.

The detailed CLI command are as follows:

Step 1     Configure the routing policy to detail the routing filter conditions and corresponding

set policy policy-statement <policy-name> term <term-name> from <filter-conditions>

set policy policy-statement <policy-name> term <term-name> to <filter-conditions>

set policy policy-statement <policy-name> term <term-name> then accept

set policy policy-statement <policy-name> term <term-name> then reject

set policy policy-statement <policy-name> term <term-name> then <actions>

Step 2     Use OSPF import or OSPF export a routing policy.

set protocols ospf4 [vrf <vrf-name>] import <policy-name>

set protocols ospf4 [vrf <vrf-name>] export <policy-name>
