To configure a service chaining EVPN policy

Steps
 
1 

Choose Policies→Residential Subscriber from the NFM-P main menu. The Residential Subscriber Policies form opens.

2 

Click Create→Service Chaining EVPN Policy or select an existing EVPN policy and click Properties. The Service Chaining EVPN Policy (Create|Edit) form opens.

Modifying an active EVPN policy is potentially service-affecting. Ensure that you consider the implications of reconfiguring the policy before you proceed.

3 

Configure the EVPN Service ID, Import Mode, and Prefix Route Resolution parameters.

These parameters cannot be changed after policy creation.

If Import Mode is set to Bridged, the Prefix Route Resolution parameter is not displayed on the policy form, but is set to Recursive by default.

The EVPN Service ID parameter value must be unique among other EVPN policies, and among services that have a service ID.

4 

Depending on the setting of the Import Mode parameter, do one of the following:

  • If the Import Mode parameter is set to Bridged, configure the parameters on the Route Distinguisher, Route Target, and VXLAN panels, or accept default values.

  • If the Import Mode parameter is set to None or Routed, configure the parameters on the Route Distinguisher, Route Target, GW Address Range, VXLAN, and IP Advertise Routes panels or accept default values.

    The Route Distinguisher and Route Target parameters have a unique mandatory syntax which is described in the tooltips for the fields.

    In order for an EVPN policy to be set to Admin State: In Service, the Route Distinguisher, Route Target, and VXLAN parameters must be configured with non-default values.

    In order for the IP Advertise Routes - Admin State parameter to be set to Enabled, the GW Address Range - Start and End parameters must be configured.

5 

If the Import Mode parameter is set to None or Routed, configure NAT pools for the EVPN policy. Associated NAT pools must be of type L2-aware, and must be configured on the base routing instance or VPRN routing instance.

  1. On the NAT Pools panel, click Create or select an existing NAT pool entry and click Properties. The NAT Pool (Create|Edit) form opens.

  2. Do one of the following:

    • Set the Router Type parameter to Base and select a pool.

    • Set the Router Type parameter to VPRN, select a VPRN service, and then select a pool.

  3. Save your changes and close the form.

6 

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.
