To configure a GRE tunnel template

Before you begin

A GRE tunnel template specifies a set of GRE encapsulation parameters to use when the primary action for ACL IP and ACL IPv6 filter policies is set to Forward (GRE Tunnel).

GRE tunnel templates are assigned to ACL IP filter policies and ACL IPv6 filter policies; see To configure an ACL IP filter policy and To configure an ACL IPv6 filter policy.

Steps
 
1 

Choose Policies→Filter→GRE Tunnel Template from the NFM-P main menu. The Filter - GRE Tunnel Template form opens.

2 

Click Create, or click Search, select an existing template, and click Properties. The GRE Tunnel Template (Create|Edit) form opens.

3 

If you are creating a new template, configure the Template Name and Description parameters, and click Apply.

The Template Name and Description parameters are configurable only when creating a new template.

4 

Click on the IPv4 tab and configure the required parameters.

5 

Click on the IPv6 tab and configure the required parameters.

6 

In the IP Destination Address panel, configure one or more IP destination addresses.

When the GRE tunnel template is assigned to an ACL IP or IPv6 filter policy, traffic matching the associated IPv4 or IPv6 filter is hashed across all available destination addresses. If no destination address is available, then matching traffic follows the configured PBR Down Action Override action, if configured; see To configure an ACL IP filter policy and To configure an ACL IPv6 filter policy.

You cannot modify an existing address in the template. You must delete the existing address and create another.

  1. Click Create. The IP Destination Address, Site (Create) form opens.

  2. Configure the IPv4 Destination Address parameter.

    You can modify address entries before the policy is saved, but not after.

  3. Save your changes and close the form. The GRE Tunnel Template (Create|Edit) form is displayed.

7 

Click OK to save the policy and close the form, or click Apply to save the policy. See To release and distribute a policy to distribute the policy to NEs.
