Configuring Additional Metrics of an Interface

Configuring Additional Metrics of an Interface


Configuring the additional metrics of a RIPng interface can change the route selection sequence.

The additional metric is the metric (hop count) to be added to the original metric of a RIPng route. You can set additional metrics for incoming and outgoing RIPng routes using commands.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. (Optional) On an Ethernet interface, run undo portswitch

    The interface is switched to Layer 3 mode.

    By default, an Ethernet interface works in Layer 2 mode.

  4. Run the following commands as required:

    • Run the ripng metricin value command to set the additional metric for receiving routes. By default, an interface does not add the metric to a received RIPng route.
    • Run the ripng metricout { value | { acl6-number | acl6-name acl6-name | ipv6-prefix ipv6-prefix-name } value1 } command to set the additional metric for advertising routes. By default, the metric that is added to the RIPng route sent by an interface is 1.
    • The ripng metricin command adds an additional metric to an incoming route. After this route is added to the routing table, its metric in the routing table changes. Running this command affects route selection on the local device and other devices on the network.
    • The ripng metricout command adds an additional metric to an outgoing route. When this route is advertised, an additional metric is added to this route, but the metric of the route in the routing table does not change. Running this command does not affect route selection on the local device but other devices on the network.
