# RIPng Interface Configuration

To create a Routing Information Protocol Next Generation (RIPng) instance, you need to configure a physical port on a security device in an IPv6 environment. An interface is a connection from the device to the network that can be addressed.

1. On the Interface (RIPng) page, enter the necessary information:

RIPng Instance: Select this option to create a RIP instance for this interface. You can create and configure a RIP instance without enabling RIP on the interface.

Protocol RIPng: Select this option to enable RIP on the interface.

Metric: Enter the metric for this interface (a value from 1 to 15).

Passive Mode: Select this option to have the interface receive but not transmit RIP packets.

Incoming Route Map Filter: Select a route map that defines the routes to be learned by RIP.

Outgoing Route Map Filter: Select a route map that defines the routes to be advertised by RIP.

Split Horizon: Select Enabled without poison reverse to cause routes learned from a neighbor to not be advertised back to the same neighbor. Select Enabled with poison reverse to cause routes that are learned from a neighbor to be advertised back to the same neighbor with a metric of 16. Select Disabled to disable split-horizon.

2. To save the settings, click Apply.
