Configuring Additional Metrics of an Interface

Context

Configuring 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 use commands to set additional metrics for incoming and outgoing RIP routes.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The interface view is displayed.
(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.

Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support switching between Layer 2 and Layer 3 modes.
Run the following commands as required:
- Run the rip metricin { value | { acl-number | acl-name acl-name | ip-prefix ip-prefix-name } value1 } 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.
