Configuring Basic RIPng Functions

Configuring Basic RIPng Functions

To use RIPng features, configure basic RIPng functions, including creating RIPng processes and enabling RIPng on interfaces.

Usage Scenario

RIPng is simple and easy to use but is less powerful in functions than OSPFv3 and IS-IS. Therefore, RIPng is widely used on small-scale networks.

Configuring basic RIPng functions is a prerequisite for building RIPng networks.

Pre-configuration Tasks

Before configuring basic RIPng functions, complete the following tasks:

  • Configure a link layer protocol.

  • Configure IP addresses for interfaces to ensure that neighboring nodes are reachable at the network layer.

  • Enable IPv6 in the system view of the NE.

Configuration Procedures

Figure 8-1 Flowchart for configuring basic RIPng functions

Creating a RIPng process

The creation of a RIPng processes is a precondition of all RIP configurations.

Usage Scenario

Before running RIPng on a NE, you need to create a RIPng process on the NE.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run ripng [ process-id ]

    The RIPng process is created, and the RIPng view is displayed.

    RIPng supports multi-instance. To bind a RIPng process to a VPN instance, you can run the ripng [ process-id ] vpn-instance vpn-instance-name command.

    NOTE:

    If you run RIPng-related commands in the interface view before enabling RIPng, the configurations take effect only after RIPng is enabled.

  3. (Optional) Run description

    A description is configured for the RIPng process.

  4. Run commit

    The configuration is submitted.

Enabling RIPng on an Interface

After an interface is associated with a RIPng process, routing information on this interface can be exchanged through RIPng.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

    The interface is on the network side of the NE. Specifically, the NE is connected to other devices through this interface. To enable the NE to learn the routes to the network segment where this interface resides, ensure that the link status of the interface is Up.

  3. Run ripng process-id enable

    RIPng is enabled on the specified interface.

    NOTE:
    • In the interface view, this command cannot be executed if IPv6 has not been enabled on the interface.

    • If the NE is connected to other devices through multiple interfaces, repeatedly perform Step 2 and Step 3.

  4. Run commit

    The configuration is submitted.

(Optional) Configuring the RIPng Priority

When multiple routing protocols are running on the same device, you can adjust the priority of RIPng for route selection.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run ripng [ process-id ]

    The RIPng process is created and the RIPng view is displayed.

  3. Run preference { preference | { route-policy route-policy-name | route-filter route-filter-name } } *

    The RIPng priority is set.

    The preference command can be used with the routing policy to set the priority for the routes that meet the matching conditions.

    After RIPng routes are delivered to the Routing Management (RM), if the RIPng priority changes, the RM updates the routing table.

  4. Run commit

    The configuration is submitted.

(Optional) Enabling Check on Zero Fields of RIPng Packets

Certain fields in RIPng packets must be 0, and these fields are called zero fields. By default, RIPng checks the zero fields of received packets and discards the packets in which any of the zero fields is not 0.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run ripng [ process-id ]

    The RIPng process is created, and the RIPng view is displayed.

  3. Run checkzero

    The check on zero fields of RIPng packets is configured.

  4. Run commit

    The configuration is submitted.

Verifying the Basic RIPng Configuration

After configuring basic RIPng functions, verify the current operating status and routing information of RIPng.

Prerequisites

Basic RIPng functions have been configured.

Procedure

  • Run the display ripng [ process-id | vpn-instance vpn-instance-name ] command to check the operating status and configuration of RIPng.
  • Run the display ripng process-id route [ destination-address destination-address [ mask-length ] ] [ interface interface-type interface-number [ neighbor-address neighbor-address ] ] command to check RIPng routes.

Example

Run the display ripng command to view the operating status and configuration of RIPng, including the RIPng process ID, priority, and whether the check on the source address is enabled.

<HUAWEI> display ripng
  Public vpn-instance name :
    RIPng process : 100
       Preference : 100
       Checkzero : Enabled
       Default Cost : 0
       Maximum number of balanced paths : 6
       Update time   : 30 sec   Age time  : 180 sec
       Suppress time : 0 sec    Garbage-Collect time : 120 sec
       Number of periodic updates sent : 0
       Number of trigger updates sent : 1
       Number of routes in database : 1
       Number of interfaces enabled : 1

Run the display ripng process-id route command to view all routes of the specified RIPng process.

<HUAWEI> display ripng 100 route
   Route Flags: A - Aging, S - Suppressed, G - Garbage-collect
