To configure a group interface on a VPRN

Prerequisites

The 7450 ESS in mixed mode, 7750 SR supports the configuration of a group interface in a VPRN.

Steps
 
1 

Choose Manage→Service→Services from the NFM-P main menu. The Manage Services form opens.

2 

Choose a VPRN and click Properties. The VPRN Service (Edit) form opens.

3 

On the service navigation tree, expand Sites→Routing Instance→Subscriber Interfaces, right-click on a subscriber interface and choose Create VPRN Group Interface, or expand the subscriber interface, right-click on a group interface and choose Properties. The VPRN Group Interface (Create|Edit) form opens.

4 

Configure the required general parameters.

The LNS parameter defines the type of group interface (regular or LNS). This parameter is set at creation time and cannot be modified. Regular group interfaces cannot configure LNS attributes and an LNS group interface does not allow PPPoE configuration or SAPs.

The Unicast RPF configuration is intended to enhance security for a MAC-only anti-spoofing configuration on the WLAN GW for soft GRE group interfaces; see To configure a WLAN GW for a VPRN group interface .
