To configure anti-spoofing filters for a VPRN L3 access interface

Steps
 
1 

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

2 

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

3 

On the service navigation tree, expand Site→L3 Access Interfaces, right-click on an L3 access interface choose Properties. The VPRN L3 Access Interface (Edit) form opens.

4 

Click on the Anti-Spoofing tab and configure the required parameters.

5 

Configure the required general parameters.

The ARP Populate parameter is configurable when all of the IP addresses of the defined static hosts on the interface are in one of the subnets configured for the interface.

6 

To configure static subscriber host entries, if subscriber entries are not available through DHCP lease management:

  1. Click on the Static Hosts tab.

  2. Click Create. The Access Interface Anti-Spoofing Static Host Display (Create) form opens.

  3. Configure the required parameters.

    Specify at least one IP address or MAC address for each static host. The values specified for the Anti-Spoofing and ARP Populate parameters determine the type of address entry that is required for the static host. For example, when you set the Anti-Spoofing parameter to Source Ip Addr, you must specify at least the IP address for the static host.

    Note:

    You can configure a static host on a SAP only when no static ARP entries exist on the IP interface.

    When the ARP Populate parameter is enabled, the IP address of the new static host must be in one of the subnets that is configured for the interface in Procedure   To assign an IP address to a VPRN L3 access interface .
