Packet type-based IPv6 interface PBR configuration example

As shown in Figure 87, configure IPv6 PBR on Switch A to forward all TCP packets received on VLAN-interface 11 to the next hop 1::2. Switch A forwards other IPv6 packets according to the routing table.

1. Configure Switch A:

   # Create VLAN 10 and VLAN 20.

   <SwitchA> system-view
   [SwitchA] vlan 10
   [SwitchA-vlan10] quit
   [SwitchA] vlan 20
   [SwitchA-vlan20] quit
   

   # Configure RIPng.

   [SwitchA] ripng 1
   [SwitchA-ripng-1] quit
   [SwitchA] interface vlan-interface 10
   [SwitchA-Vlan-interface10] ipv6 address 1::1 64
   [SwitchA-Vlan-interface10] ripng 1 enable
   [SwitchA-Vlan-interface10] quit
   [SwitchA] interface vlan-interface 20
   [SwitchA-Vlan-interface20] ipv6 address 2::1 64
   [SwitchA-Vlan-interface20] ripng 1 enable
   [SwitchA-Vlan-interface20] quit
   

   # Configure ACL 3001 to match TCP packets.

   [SwitchA] acl ipv6 number 3001
   [SwitchA-acl6-adv-3001] rule permit tcp
   [SwitchA-acl6-adv-3001] quit
   

   # Configure Node 5 for policy aaa to forward TCP packets to next hop 1::2.

   [SwitchA] ipv6 policy-based-route aaa permit node 5
   [SwitchA-pbr6-aaa-5] if-match acl 3001
   [SwitchA-pbr6-aaa-5] apply next-hop 1::2
   [SwitchA-pbr6-aaa-5] quit
   

   # Configure IPv6 interface PBR by applying policy aaa to VLAN-interface 11.

   [SwitchA] interface vlan-interface 11
   [SwitchA-Vlan-interface11] ipv6 address 10::2 64
   [SwitchA-Vlan-interface11] undo ipv6 nd ra halt
   [SwitchA-Vlan-interface11] ripng 1 enable
   [SwitchA-Vlan-interface11] ipv6 policy-based-route aaa
   

2. Configure Switch B:

   # Create VLAN 10.

   <SwitchB> system-view
   [SwitchB] vlan 10
   [SwitchB-vlan10] quit
   

   # Configure RIPng.

   [SwitchB] ripng 1
   [SwitchB-ripng-1] quit
   [SwitchB] interface vlan-interface 10
   [SwitchB-Vlan-interface10] ipv6 address 1::2 64
   [SwitchB-Vlan-interface10] ripng 1 enable
   [SwitchB-Vlan-interface10] quit
   

3. Configure Switch C:

   # Create VLAN 20.

   <SwitchC> system-view
   [SwitchC] vlan 20
   [SwitchC-vlan20] quit
   

   # Configure RIPng.

   [SwitchC] ripng 1
   [SwitchC-ripng-1] quit
   [SwitchC] interface vlan-interface 20
   [SwitchC-Vlan-interface20] ipv6 address 2::2 64
   [SwitchC-Vlan-interface20] ripng 1 enable
   [SwitchC-Vlan-interface20] quit
   

# Enable IPv6 and configure the IPv6 address 10::3 for Host A.

C:\>ipv6 install
Installing...
Succeeded.
C:\>ipv6 adu 4/10::3

# On Host A, Telnet to Switch B that is directly connected to Switch A. The operation succeeds.

# On Host A, Telnet to Switch C that is directly connected to Switch A. The operation fails.

# Ping Switch C from Host A. The operation succeeds.

Telnet uses TCP, and ping uses ICMP. The preceding results show that all TCP packets arriving on VLAN-interface 11 of Switch A are forwarded to next hop 1::2, and other packets are forwarded through VLAN-interface 20. The IPv6 interface PBR configuration is effective.
