Configuring RIPng basic functions

In Figure 102, all switches run RIPng. Configure Switch B to filter the route (3::/64) learned from Switch C, which means the route will not be added to the routing table of Switch B, and Switch B will not forward it to Switch A.

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

2. Configure basic RIPng functions:

   # 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.

   <SwitchB> system-view
   [SwitchB] ripng 1
   [SwitchB-ripng-1] quit
   [SwitchB] interface vlan-interface 200
   [SwitchB-Vlan-interface200] ripng 1 enable
   [SwitchB-Vlan-interface200] quit
   [SwitchB] interface vlan-interface 100
   [SwitchB-Vlan-interface100] ripng 1 enable
   [SwitchB-Vlan-interface100] 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 routing table on Switch B.

3. Configure route filtering:

   # Configure Switch B to filter incoming and outgoing route.

   [SwitchB] acl ipv6 number 2000
   [SwitchB-acl6-basic-2000] rule deny source 3::/64
   [SwitchB-acl6-basic-2000] rule permit
   [SwitchB-acl6-basic-2000] quit
   [SwitchB] ripng 1
   [SwitchB-ripng-1] filter-policy 2000 import
   [SwitchB-ripng-1] filter-policy 2000 export
