Packet type-based IPv6 interface PBR configuration example
Network requirements
As shown in Figure 119, 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.

Configuration procedure
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 advanced 3001 [SwitchA-acl-ipv6-adv-3001] rule permit tcp [SwitchA-acl-ipv6-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
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
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
Verifying the configuration
# 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 results show the following:
All TCP packets arriving on VLAN-interface 11 of Switch A are forwarded to next hop 1::2.
Other packets are forwarded through VLAN-interface 20.
The IPv6 interface PBR configuration is effective.
