Basic RIPng configuration example

As shown in Figure 85, Switch A, Switch B, and Switch C run RIPng. Configure Switch B to filter the route 2::/64 learned from Switch A and to forward only the route 4::/64 to Switch A.

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

2. Configure basic RIPng:

   # Configure Switch A.

   <SwitchA> system-view
   [SwitchA] ripng 1
   [SwitchA-ripng-1] quit
   [SwitchA] interface vlan-interface 100
   [SwitchA-Vlan-interface100] ripng 1 enable
   [SwitchA-Vlan-interface100] quit
   [SwitchA] interface vlan-interface 400
   [SwitchA-Vlan-interface400] ripng 1 enable
   [SwitchA-Vlan-interface400] quit
   

   # Configure Switch B.

   <SwitchA> system-view
   [SwitchA] ripng 1
   [SwitchA-ripng-1] quit
   [SwitchA] interface vlan-interface 100
   [SwitchA-Vlan-interface100] ripng 1 enable
   [SwitchA-Vlan-interface100] quit
   [SwitchA] interface vlan-interface 400
   [SwitchA-Vlan-interface400] ripng 1 enable
   [SwitchA-Vlan-interface400] quit
   

   # Configure Switch C.

   <SwitchC> system-view
   [SwitchC] ripng 1
   [SwitchC-ripng-1] quit
   [SwitchC] interface vlan-interface 200
   [SwitchC-Vlan-interface200] ripng 1 enable
   [SwitchC-Vlan-interface200] quit
   [SwitchC] interface vlan-interface 500
   [SwitchC-Vlan-interface500] ripng 1 enable
   [SwitchC-Vlan-interface500] quit
   [SwitchC] interface vlan-interface 600
   [SwitchC-Vlan-interface600] ripng 1 enable
   [SwitchC-Vlan-interface600] quit
   

   # Display the RIPng routing table on Switch B.

   [SwitchB] display ripng 1 route

3. Configure route filtering:

   # Use IPv6 prefix lists on Switch B to filter received and redistributed routes.

   [SwitchB] ipv6 prefix-list aaa permit 4:: 64
   [SwitchB] ipv6 prefix-list bbb deny 2:: 64
   [SwitchB] ipv6 prefix-list bbb permit :: 0 less-equal 128
   [SwitchB] ripng 1
   [SwitchB-ripng-1] filter-policy prefix-list aaa export
   [SwitchB-ripng-1] filter-policy prefix-list bbb import
   [SwitchB-ripng-1] quit
   

   # Display RIPng routing tables on Switch B and Switch A.

   [SwitchB] display ripng 1 route
