Configuration Guide - IP Unicast Routing

S7700 and S9700 V200R011C10

This document describes IP Unicast Routing configurations supported by the switch, including the principle and configuration procedures of IP Routing Overview, Static Route, RIP, RIPng, OSPF, OSPFv3, IS-IS(IPv4), IS-IS(IPv6), BGP, Routing Policy ,and PBR, and provides configuration examples.

Example for Configuring Basic IS-IS IPv6 Functions

Networking Requirements

In Figure 8-2, the four switches on the IPv6 network need to communicate with each other. SwitchA and SwitchB can only process a small amount of data.

Figure 8-2  Networking diagram of basic IS-IS IPv6 feature

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure IPv6 addresses on interfaces of each switch so that the switches can be interconnected.

  2. Enable IS-IS on each switch so that the switches can be interconnected. Configure SwitchA and SwitchB as Level-1 switches to enable them to maintain less data.

Procedure

  1. Configure VLANs that interfaces belong to.

    # Configure SwitchA. Ensure that the configurations of SwitchB, SwitchC, and SwitchD are the same as the configuration of SwitchA.

    <HUAWEI> system-view
    [HUAWEI] sysname SwitchA
    [SwitchA] vlan batch 10
    [SwitchA] interface gigabitethernet 1/0/0
    [SwitchA-GigabitEthernet1/0/0] port link-type trunk
    [SwitchA-GigabitEthernet1/0/0] port trunk allow-pass vlan 10
    [SwitchA-GigabitEthernet1/0/0] quit

  2. Enable the capability of IPv6 forwarding and configure IPv6 address for each interface.

    # Configure SwitchA. Ensure that the configurations of SwitchB, SwitchC, and SwitchD are the same as the configuration of SwitchA.

    [SwitchA] ipv6
    [SwitchA] interface vlanif 10
    [SwitchA-Vlanif10] ipv6 enable
    [SwitchA-Vlanif10] ipv6 address fc00:0:0:10::2/64
    [SwitchA-Vlanif10] quit

  3. Configure IS-IS.

    # Configure SwitchA.

    [SwitchA] isis 1
    [SwitchA-isis-1] is-level level-1
    [SwitchA-isis-1] network-entity 10.0000.0000.0001.00
    [SwitchA-isis-1] ipv6 enable
    [SwitchA-isis-1] quit
    [SwitchA] interface vlanif 10
    [SwitchA-Vlanif10] isis ipv6 enable 1
    [SwitchA-Vlanif10] quit

    # Configure SwitchB.

    [SwitchB] isis 1 
    [SwitchB-isis-1] is-level level-1
    [SwitchB-isis-1] network-entity 10.0000.0000.0002.00
    [SwitchB-isis-1] ipv6 enable
    [SwitchB-isis-1] quit
    [SwitchB] interface vlanif 20
    [SwitchB-Vlanif20] isis ipv6 enable 1
    [SwitchB-Vlanif20] quit

    # Configure SwitchC.

    [SwitchC] isis 1
    [SwitchC-isis-1] network-entity 10.0000.0000.0003.00
    [SwitchC-isis-1] ipv6 enable
    [SwitchC-isis-1] quit
    [SwitchC] interface vlanif 10
    [SwitchC-Vlanif10] isis ipv6 enable 1
    [SwitchC-Vlanif10] quit
    [SwitchC] interface vlanif 20
    [SwitchC-Vlanif20] isis ipv6 enable 1
    [SwitchC-Vlanif20] quit
    [SwitchC] interface vlanif 30
    [SwitchC-Vlanif30] isis ipv6 enable 1
    [SwitchC-Vlanif30] isis circuit-level level-2
    [SwitchC-Vlanif30] quit

    # Configure SwitchD.

    [SwitchD] isis 1 
    [SwitchD-isis-1] is-level level-2
    [SwitchD-isis-1] network-entity 20.0000.0000.0004.00
    [SwitchD-isis-1] ipv6 enable
    [SwitchD-isis-1] quit
    [SwitchD] interface vlanif 30
    [SwitchD-Vlanif30] isis ipv6 enable 1
    [SwitchD-Vlanif30] quit
    [SwitchD] interface vlanif40
    [SwitchD-Vlanif40] isis ipv6 enable 1
    [SwitchD-Vlanif40] quit

  4. Verify the configuration.

    # Check the IS-IS routing table of SwitchA.

    [SwitchA] display isis route
