逐步过程
以下示例要求您在配置层次结构中的各个级别上导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。
要配置 IS-IS 组播拓扑：
使用
ipv4-multicast语句为 IS-IS 启用组播拓扑。路由器 R1、R2 和 R3
[edit protocols isis] user@host# set traceoptions file isis size 5m world-readable user@host# set traceoptions flag error user@host# set topologies ipv4-multicast
使用
ipv4-multicast-metric语句在第一个 SONET/SDH 接口上启用组播指标。路由器 R1
[edit protocols isis interface so-0/0/0 ] user@R1# set level 1 metric 15 user@R1# set level 1 ipv4-multicast-metric 18 user@R1# set level 2 metric 20 user@R1# set level 2 ipv4-multicast-metric 14
路由器 R2
[edit protocols isis interface so-0/0/0] user@R2# set level 1 metric 13 user@R2# set level 1 ipv4-multicast-metric 12 user@R2# set level 2 metric 29 user@R2# set level 2 ipv4-multicast-metric 23
路由器 R3
[edit protocols isis interface so-0/0/0] user@R3# set level 1 metric 19 user@R3# set level 1 ipv4-multicast-metric 11 user@R3# set level 2 metric 27 user@R3# set level 2 ipv4-multicast-metric 21
使用
ipv4-multicast-metric语句在第二个 sonet 接口上启用组播指标。路由器 R1
[edit protocols isis interface so-1/0/0] user@R1# set level 1 metric 13 user@R1# set level 1 ipv4-multicast-metric 12 user@R1# set level 2 metric 29 user@R1# set level 2 ipv4-multicast-metric 23
路由器 R2
[edit protocols isis interface so-1/0/0] user@R2# set level 1 metric 14 user@R2# set level 1 ipv4-multicast-metric 18 user@R2# set level 2 metric 32 user@R2# set level 2 ipv4-multicast-metric 26
路由器 R3
[edit protocols isis interface so-1/0/0] user@R3# set level 1 metric 16 user@R3# set level 1 ipv4-multicast-metric 26 user@R3# set level 2 metric 30 user@R3# set level 2 ipv4-multicast-metric 20
禁用带外管理端口 fxp0。
路由器 R1、R2 和 R3
[edit protocols isis] user@host# set interface fxp0.0 disable
完成路由器配置后，请提交配置。
路由器 R1、R2 和 R3
[edit] user@host# commit
结果
在配置模式下，使用 show protocols isis 语句确认您的配置。如果输出未显示预期的配置，请重复此示例中的说明，以更正配置。
