Configuring Network Topology for Gateways

If the gateway is a member of a VPN community, to expose networks behind this gateway to other members, you must configure network topology settings for the gateway. The internal network topology is the list of internal networks or IP addresses behind this gateway.

When you configure a list of networks that are part of the internal network topology, you can also configure a list of networks which is excluded.

Use case: If two gateways are in the same community and protect the same parts of the network, there is overlap. You can separate the topologies for gateways in a community and exclude part of the network.

Note - To support this feature, the firmware on the gateway must be version R77.20.80 and higher.

1. Go to Home > Gateways.

8. To exclude a network from the internal network topology, click Exclude the following networks and enter the information in the Internal Network Edit window.

9. To edit the settings, click the network's name.

   The Internal Network Edit window opens.

10. To delete a network's settings, select the check box next to the network and click Delete.
