Configuring Additional Metrics of an Interface

Configuring Additional Metrics of an Interface


Configuring the additional metrics on a RIP interface can change the route selection sequence.

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


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. 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.

    The mode switching function takes effect when the interface only has attribute configurations (for example, shutdown and description configurations). Alternatively, if configuration information supported by both Layer 2 and Layer 3 interfaces exists (for example, mode lacp and lacp system-id configurations), no configuration that is not supported after the working mode of the interface is switched can exist. If unsupported configurations exist on the interface, delete the configurations first and then run the undo portswitch command.


    If many Ethernet interfaces need to be switched to Layer 3 mode, run the undo portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view to switch these interfaces to Layer 3 mode in batches.

  4. Run the following commands as required:

    • Run the rip metricin value command to set the additional metric for receiving routes.
    • Run the rip metricout { value | { acl-number | acl-name acl-name | ip-prefix ip-prefix-name } value1 } command to set the additional metric for advertising routes.
    • The rip metricin command is used to add 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 rip metricout command is used to add 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 affects route selection on other devices in the network.

  5. Run commit

    The configuration is committed.
