Testing Routing Policies

Before applying a routing policy in a live environment, you can use the test policy command to ensure that the policy produces the results that you expect. The test policy command uses the following syntax:



user@host> test policy policy-name prefix

For more information about test commands, see the JUNOS Routing Protocols and Policies Command Reference.

Example: Testing a Routing Policy

Test the following policy, which looks for unwanted routes and rejects them:



[edit policy-options]
policy-statement reject-unwanted-routes {


term drop-these-routes {


from {
route-filter 0/0 exact;
route-filter 10/8 orlonger;
route-filter 172.16/12 orlonger;
route-filter 192.168/16 orlonger;
route-filter 224/3 orlonger;
}


then reject;
}


}

Test this policy against all routes in the routing table:



user@host> test policy reject-unwanted-routes
0/0

Test this policy against a specific set of routes:



user@host> test policy reject-unwanted-routes 10.49.0.0/16
