示例：分隔聚合以太网接口上的 Demux 订阅者的目标组播流量
此示例演示如何将目标组播流量与目标单播流量分离，并通过使用 OIF 图将组播流量发送到不同接口。
要求
配置此示例之前，请确保配置接口的分配类型。有关 说明，请参阅 在聚合以太网接口上为 Demux 订阅者配置分发类型 。
概述
此示例已在路由器上配置了目标流量分配。动态创建的接口各自承载其单播流量，但所有组播流量均发送至 ge-5/3/9.0 接口。
配置
CLI快速配置
要快速配置此示例，请复制以下命令，将其粘贴到文本文件中，删除所有换行符，更改详细信息，以匹配网络配置，然后将命令复制并粘贴到 层次结构级别的 CLI [edit] 中。

配置 OIF 映射策略
逐步过程
以下示例要求您在配置层次结构中导航各个级别。
要配置 OIF 映射：
访问路由器策略选项：
[edit] user@host#edit policy-options
编辑策略语句。
[edit policy-options] user@host edit policy-statement OIF-v4-all
创建用于将传入组播信息流映射到特定接口的术语。
[edit policy-options OIF-v4-all] user@host edit term oif539
定义术语的匹配条件。在这种情况下，术语匹配 192.168.20.0/4 或更长任何路由前缀（所有组播流量）。
[edit policy-options OIF-v4-all term oif539] user@host set from route-filter 192.168.20.0/4 orlonger
-
定义术语的操作。在这种情况下，发生匹配时，术语接受信息流，并映射到接口 ge-5/3/9.0。
[edit policy-options OIF-v4-all term oif539] user@host set then map-to-interface ge-5/3/9.0 user@host set then accept
结果
发出命令以确认您的 show policy-options 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。
[edit]
user@host# show policy-options
policy-statement OIF-v4-all {
term oif539 {
from {
route-filter 192.168.20.0/4 orlonger;
}
then {
map-to-interface ge-5/3/9.0;
accept;
}
}
}
配置 DHCP VLAN 动态配置文件
逐步过程
以下示例要求您在配置层次结构中导航各个级别。
要配置 DHCP VLAN 动态配置文件以用于客户端访问：
创建动态 VLAN 多路复用配置文件。
[edit] user@host#edit dynamic-profiles dhcp-vlan-prof
编辑动态配置文件接口。
[edit dynamic-profiles dhcp-vlan-prof] user@host edit interfaces $junos-ifd-name
编辑接口单元动态变量。
[edit dynamic-profiles demux-vlan-prof interfaces $junos-ifd-name] user@host edit unit $junos-underlying-interface-unit
编辑接口族。
[edit dynamic-profiles demux-vlan-prof interfaces $junos-ifd-name unit $junos-underlying-interface-unit] user@host edit family inet
定义环路地址。
[edit dynamic-profiles demux-vlan-prof interfaces $junos-ifd-name unit $junos-underlying-interface-unit ] user@host set unnumbered-address lo0.0 preferred-source-address 10.20.0.2
结果
发出 命令以确认您的 show dynamic-profiles 配置。如果 dhcp-vlan-prof 动态配置文件的输出未显示预期的配置，请重复此示例中的说明，以更正配置。
[edit]
user@host# show dynamic-profiles
dhcp-vlan-prof {
interfaces {
"$junos-interface-ifd-name" {
unit "$junos-underlying-interface-unit" {
family inet {
unnumbered-address lo0.0 preferred-source-address 10.20.0.2;
}
}
}
}
}
配置 VLAN Demux 动态配置文件
逐步过程
以下示例要求您在配置层次结构中导航各个级别。
要配置 OIF 映射：
创建动态 VLAN 多路复用配置文件。
[edit] user@host#edit dynamic-profiles demux-vlan-prof
编辑动态配置文件 demux0 接口。
[edit dynamic-profiles demux-vlan-prof] user@host edit interfaces demux0
编辑接口单元动态变量。
[edit dynamic-profiles demux-vlan-prof interfaces demux0] user@host edit unit $junos-interface-unit
指定 VLAN ID 动态变量。
[edit dynamic-profiles demux-vlan-prof interfaces demux0 unit �$junos-interface-unit�] user@host set vlan-id $junos-vlan-id
访问多路复用选项。
[edit dynamic-profiles demux-vlan-prof interfaces demux0 unit �$junos-interface-unit�] user@host edit demux-options
定义多路复用底层接口。
[edit dynamic-profiles demux-vlan-prof interfaces demux0 unit �$junos-interface-unit� demux-options] user@host set underlying-interface $junos-interface-ifd-name
指定使用目标分配来动态创建 VLAN。
[edit dynamic-profiles demux-vlan-prof interfaces demux0 unit �$junos-interface-unit�] user@host set targeted-distribution

[edit dynamic-profiles demux-vlan-prof interfaces demux0 unit �$junos-interface-unit�] user@host edit family inet
定义环路地址。
[edit dynamic-profiles demux-vlan-prof interfaces demux0 unit �$junos-interface-unit� family inet] user@host set unnumbered-address lo0.0 preferred-source-address 10.20.0.2
编辑动态配置文件 IGMP 协议。
[edit dynamic-profiles demux-vlan-prof] user@host edit protocols igmp
在动态创建的接口上启用 IGMP。
[edit dynamic-profiles demux-vlan-prof protocols igmp] user@host edit interface $junos-interface-name
指定您希望动态创建接口使用的 IGMP 版本。
[edit dynamic-profiles demux-vlan-prof protocols igmp interface $junos-interface-name] user@host set version 2
指定要动态创建 IGMP 接口使用的 OIF 映射。
[edit dynamic-profiles demux-vlan-prof protocols igmp interface $junos-interface-name] user@host set oif-map OIF-v4-all

指定接口接受来自任何子网上主机的 IGMP 报告。
[edit dynamic-profiles demux-vlan-prof protocols igmp interface $junos-interface-name] user@host set promiscuous-mode
结果
发出命令以确认您的 show dynamic-profiles 配置。如果 dhcp-vlan-prof 动态配置文件的输出未显示预期的配置，请重复此示例中的说明，以更正配置。
[edit]
user@host# show dynamic-profiles
demux-vlan-prof {
interfaces {
demux0 {
unit "$junos-interface-unit" {
vlan-id "$junos-vlan-id";
demux-options {
