Configuring RIPng route redistribution

Network requirements

Two RIPng processes are running on Switch B, which communicates with Switch A through RIPng 100 and with Switch C through RIPng 200.

Configure route redistribution on Switch B, letting the two RIPng processes redistribute routes from each other. Set the default cost of redistributed routes from RIPng 200 to 3.

Configuration procedure

  1. Configure IPv6 addresses for the interfaces. (Details not shown.)

  2. Configure RIPng basic functions:

    # Enable RIPng 100 on Switch A.

    <SwitchA> system-view
    [SwitchA] ripng 100
    [SwitchA-ripng-100] quit
    [SwitchA] interface vlan-interface 100
    [SwitchA-Vlan-interface100] ripng 100 enable
    [SwitchA-Vlan-interface100] quit
    [SwitchA] interface vlan-interface 200
    [SwitchA-Vlan-interface200] ripng 100 enable
    [SwitchA-Vlan-interface200] quit
    

    # Enable RIP 100 and RIP 200 on Switch B.

    <SwitchB> system-view
    [SwitchB] ripng 100
    [SwitchB-ripng-100] quit
    [SwitchB] interface vlan-interface 100
    [SwitchB-Vlan-interface100] ripng 100 enable
    [SwitchB-Vlan-interface100] quit
    [SwitchB] ripng 200
    [SwitchB-ripng-200] quit
    [SwitchB] interface vlan-interface 300
    [SwitchB-Vlan-interface300] ripng 200 enable
    [SwitchB-Vlan-interface300] quit
    

    # Enable RIPng 200 on Switch C.

    <SwitchC> system-view
    [SwitchC] ripng 200
    [SwitchC] interface vlan-interface 300
    [SwitchC-Vlan-interface300] ripng 200 enable
    [SwitchC-Vlan-interface300] quit
    [SwitchC] interface vlan-interface 400
    [SwitchC-Vlan-interface400] ripng 200 enable
    [SwitchC-Vlan-interface400] quit
    

    # Display the routing table on Switch A.

    [SwitchA] display ipv6 routing-table

  3. Configure RIPng route redistribution:

    # Configure route redistribution between the two RIPng processes on Switch B.

    [SwitchB] ripng 100
    [SwitchB-ripng-100] default cost 3
    [SwitchB-ripng-100] import-route ripng 200
    [SwitchB-ripng-100] quit
    [SwitchB] ripng 200
    [SwitchB-ripng-200] import-route ripng 100
    [SwitchB-ripng-200] quit
    

    # Display the routing table on Switch A.

    [SwitchA] display ipv6 routing-table
