S1720, S2700, S5700, and S6720 V200R011C10 Configuration Guide - IP Service

This document describes the configurations of IP Service, including IP address, ARP, DHCP, DHCP policy VLAN, DNS, mDNS gateway, mDNS relay, UDP Helper, IP performance optimization, IPv6, DHCPv6, IPv6 DNS, IPv6 over IPv4 tunnel, and IPv4 over IPv6 tunnel.

Networking Requirements

In Figure 11-16, GE0/0/1 of SwitchA connects to GE0/0/1 of SwitchB. The two interfaces correspond to their VLANIF interfaces (VLANIF 100). You need to configure IPv6 addresses for the VLANIF interfaces and check the Layer 3 interconnection between the interfaces.

IPv6 addresses for the VLANIF interfaces are fc00:1::1/64 and fc00:1::2/64.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Enable the IPv6 forwarding function on SwitchA and SwitchB.

  2. Configure IPv6 addresses for the interfaces.

Procedure

  1. Enable the IPv6 forwarding function on switches.

    # Configure SwitchA.

    <HUAWEI> system-view
[HUAWEI] sysname SwitchA
[SwitchA] ipv6

    # Configure SwitchB.

    <HUAWEI> system-view
[HUAWEI] sysname SwitchB
[SwitchB] ipv6

  2. Configure IPv6 addresses for the interfaces.

    # Configure SwitchA.

    [SwitchA] vlan 100
[SwitchA-vlan100] quit
[SwitchA] interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] port link-type hybrid
[SwitchA-GigabitEthernet0/0/1] port hybrid pvid vlan 100
[SwitchA-GigabitEthernet0/0/1] port hybrid untagged vlan 100
[SwitchA-GigabitEthernet0/0/1] quit
[SwitchA] interface vlanif 100
[SwitchA-Vlanif100] ipv6 enable
[SwitchA-Vlanif100] ipv6 address fc00:1::1/64
[SwitchA-Vlanif100] quit

    # Configure SwitchB.

    [SwitchB] vlan 100
[SwitchB-vlan100] quit
[SwitchB] interface gigabitethernet 0/0/1
[SwitchB-GigabitEthernet0/0/1] port link-type hybrid
[SwitchB-GigabitEthernet0/0/1] port hybrid pvid vlan 100
[SwitchB-GigabitEthernet0/0/1] port hybrid untagged vlan 100
[SwitchB-GigabitEthernet0/0/1] quit
[SwitchB] interface vlanif 100
[SwitchB-Vlanif100] ipv6 enable
[SwitchB-Vlanif100] ipv6 address fc00:1::2/64
[SwitchB-Vlanif100] quit

  3. Verify the configuration.

    # Check interface information on SwitchA.

    [SwitchA] display ipv6 interface vlanif 100
Vlanif100 current state : UP
IPv6 protocol current state : UP
IPv6 is enabled, link-local address is FE80::218:20FF:FE00:83
  Global unicast address(es):
    FC00:1::1, subnet is FC00:1::/64
  Joined group address(es):
    FF02::1:FF00:1
    FF02::1:FF00:83
    FF02::2
    FF02::1
  MTU is 1500 bytes
  ND DAD is enabled, number of DAD attempts: 1
  ND reachable time is 30000 milliseconds
  ND retransmit interval is 1000 milliseconds
  ND stale time is 1200 seconds

    # Check interface information on SwitchB.

    [SwitchB] display ipv6 interface vlanif 100
Vlanif100 current state : UP
IPv6 protocol current state : UP
IPv6 is enabled, link-local address is FE80::2E0:FCFF:FE33:11
  Global unicast address(es):
    FC00:1::2, subnet is FC00:1::/64
  Joined group address(es):
    FF02::1:FF00:2
    FF02::1:FF33:11
    FF02::2
    FF02::1
  MTU is 1500 bytes
  ND DAD is enabled, number of DAD attempts: 1
  ND reachable time is 30000 milliseconds
  ND retransmit interval is 1000 milliseconds
  ND stale time is 1200 seconds

    # Ping the IPv6 address of SwitchB from SwitchA.

    [SwitchA] ping ipv6 FC00:1::2
  PING FC00:1::2 : 56  data bytes, press CTRL_C to break
    Reply from FC00:1::2
    bytes=56 Sequence=1 hop limit=64  time = 12 ms
    Reply from FC00:1::2
    bytes=56 Sequence=2 hop limit=64  time = 3 ms
    Reply from FC00:1::2
    bytes=56 Sequence=3 hop limit=64  time = 3 ms
    Reply from FC00:1::2
    bytes=56 Sequence=4 hop limit=64  time = 3 ms
    Reply from FC00:1::2
    bytes=56 Sequence=5 hop limit=64  time = 3 ms

  --- FC00:1::2 ping statistics ---
    5 packet(s) transmitted
