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
 

Choose Policies→Filter→Redirect Filter from the NFM-P main menu. The Redirect Filter Policies form opens.


Click Create or select an existing policy and click Properties. The Redirect Filter Policy (Create|Edit) form opens.


Configure the parameters as required.


If you configured the Router Instance Type parameter to VPRN, click Select to assign a VPRN pointer to the policy.


Click on the Destination Addresses tab and click Create. The Destination (Create) form opens.


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.


Perform one or more of the following test types:

  1. Configure an SNMP test:

    1. Click on the SNMP Tests tab and click Create. The SNMP Test (Create) form opens.

    2. Configure the required parameters.

    3. Click on the SNMP Responses tab and click Create. The SNMP Response (Create) form opens.

    4. Configure the required parameters.

    5. Save your changes and close the form.

    6. Repeat 3 to 5 to create addition SNMP responses for the SNMP test.

    7. Repeat 1 to 6 to create addition SNMP tests for the redirect filter.

  2. Configure a URL test:

    1. Click on the URL Tests tab and click Create. The URL Test (Create) form opens.

    2. Configure the required parameters.

    3. Click on the URL Responses tab and click Create. The URL Response (Create) form opens.

    4. Configure the required parameters.

    5. Save your changes and close the form.

    6. Repeat 3 to 5 to create addition URL responses for the URL test.

    7. Repeat 1 to 6 to create addition URL tests for the redirect filter.

  3. Configure a Ping test:

    1. Enable the Enable Ping Test parameter.

    2. Click on the Ping Test tab.

    3. Configure the required parameters.

    4. Save your changes and close the form.

    For supporting NEs, the results of Ping tests can be shared among multiple destination addresses, when a redirect policy binding is configured for those addresses. See To configure a Redirect Policy Binding.


Save your changes and close the form.


Repeat Step 2 to Step 8 to create additional IPv4 or IPv6 destination addresses as required.

See To release and distribute a policy to release and distribute the policy to NEs.

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.
