To configure a Redirect Filter policy
Purpose
Redirect Filter policies allow specifying multiple redirect target destinations and defining health check test methods used to validate the ability for a given destination to receive redirected traffic. This destination monitoring allows a router to react to target destination failures.
Steps
1 |
Choose Policies→Filter→Redirect Filter from the NFM-P main menu. The Redirect Filter Policies form opens. |
2 |
Click Create or select an existing policy and click Properties. The Redirect Filter Policy (Create|Edit) form opens. |
3 |
Configure the parameters as required. |
4 |
If you configured the Router Instance Type parameter to VPRN, click Select to assign a VPRN pointer to the policy. |
5 |
Click on the Destination Addresses tab and click Create. The Destination (Create) form opens. |
6 |
Configure the parameters as required. If you enable the Enable Unicast Route Reachability Test parameter, no other health check test can be performed. Go to Step 8. If you set the Address Type parameter to IPv4, go to Step 7. For IPv6, you can only perform Step 7 c. |
7 |
Perform one or more of the following test types:
|
8 |
Save your changes and close the form. |
9 |
Repeat Step 2 to Step 8 to create additional IPv4 or IPv6 destination addresses as required. |
10 |
See To release and distribute a policy to release and distribute the policy to NEs. |
11 |
To associate a newly-created IPv4 redirect filter policy with an ACL IPv4 filter policy, see To configure an ACL IP filter policy. For an IPv6 redirect filter policy, see To configure an ACL IPv6 filter policy. You must set the Action parameter to the forward (Redirect Filter) option to enable an association. The ACL Filter Entries tab on the Redirect Filter Policy form lists all such associations for distributed policies. |
12 |
When a Redirect Filter policy has been distributed to the required NEs, you can open local definitions from the Local Definitions tab of the global policy and examine the tests for each contained destination. A Refresh button is available on the individual test property forms to get the Last Response details. |

Close the forms. End of steps |
