S9300, S9300X V200R019C10 配置指南-IP单播路由

本文档介绍了IP单播路由的配置，具体包括IP路由概述、静态路由配置、RIP配置、RIPng配置、OSPF配置、OSPFv3配置、IS-IS（IPv4）配置、IS-IS（IPv6）配置、BGP配置、路由策略配置、IP路由表管理、策略路由配置和路由监控组配置。

配置IS-IS IPv6的基本功能示例

配置IS-IS IPv6的基本功能示例

组网需求

如图8-1所示，在IPv6拓扑网络中有4台交换机，现要求在这4台交换机上实现网络互联，并且因为SwitchA和SwitchB性能相对较低，所以还要使这两台交换机处理相对较少的数据信息。

图8-1 配置IS-IS的IPv6特性基本功能组网图

配置思路

采用如下的思路配置IS-IS IPv6的基本功能：

  1. 在各交换机的接口上配置IPv6地址，实现网络可达。

  2. 在各交换机上配置IS-IS for IPv6基本功能，实现网络互联。其中，将SwitchA、SwitchB设为Level-1设备，从而使得这两台交换机可以维护相对少量的数据信息。

操作步骤

  1. 配置各接口所属VLAN

    # 配置SwitchA。SwitchB、SwitchC和SwitchD的配置与SwitchA类似。

    <Quidway> system-view
[Quidway] 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. 使能IPv6转发能力，配置各接口的IPv6地址

    # 配置SwitchA。SwitchB、SwitchC和SwitchD的配置与SwitchA类似。

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

  3. 配置IS-IS

    # 配置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

    # 配置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

    # 配置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

    # 配置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. 验证配置结果
