Cisco IOS software supports the following protocols to implement IP multicast routing: Internet Group Management Protocol (IGMP) is used among hosts on a LAN and the routers (and multilayer switches) on that LAN
ip multicast-routing distributed Enable IP multicast distributed switching. Step 3 interface interface-id Specify the Layer 3 interface on which you want to enable multicast routing, and enter interface configuration mode. The specified interface must be one of the following: •A routed po...
组播路由和转发与单播路由和转发类似,首先每个组播路由协议都各自建立并维护了一张协议路由表。各组播路由协议的组播路由信息经过综合形成一个总的组播路由表(Multicast Routing-Table)。最后,路由器根据组播路由和转发策略,从组播路由表中选出最优的组播路由,并下发到组播转发表(Multicast Forwarding-Table),直接用于控制...
执行命令multicast ipv6 boundary { ipv6-group-address ipv6-group-mask-length | scope scope-id },配置IPv6组播转发边界。 检查配置结果 IPv6组播转发边界配置成功后,查看组播路由表(IPv6)、接口的组播边界信息,确保IPv6组播网络正常运行。 使用命令display multicast ipv6 routing-table [ ipv6-source-address...
MLD:组播侦听者发现协议(MulticastListenerDiscovery) 4总体框架 4.1位置信息映射的IPv6网络系统架构 位置信息映射的IPv6网络系统如图3所示。对于端系统而言,位置信息映射的IPv6网络不会改 变通信系统中的数据包收发基本系统,对于管理子系统而言,增加了基于位置进行编址的方法,对 于数据包转发而言,增加了基于位置进行寻址...
For IP multicasting to span routers across an internetwork, multicast routing protocols are used by routers to communicate host group information so that each router supporting multicast forwarding is aware of which networks contain members of which host groups. IGMP is defined in RFCs 1112 and 2236...
routingA brief technical overview of IP multicast and IP multicast routing are provided.Then IP multicast concepts and technical features are presented . Finally IP multicast delivery, addressing and approaches to multicast routing are discussed.
1.1.17 reset multicast routing-table 1 组播路由与转发 · 组播路由与转发功能中所指的“接口”为三层口,包括VLAN接口、三层以太网端口等。三层以太网端口是指被配置为三层模式的以太网端口,有关以太网端口模式切换的操作,请参见“二层技术-以太网交换配置指导”中的“以太网端口配置”。 · 本系列交换机未形成...
ip multicast-routing 1. **答案判别**:题目给出具体命令"ip multicast-routing",为标准组播路由全局启用命令(如Cisco设备),存在明确答案。 2. **完整性判断**:题目明确提供完整的命令格式,且语法正确,不存在字段缺失或歧义,满足完整性条件。 3. **输出逻辑**:由于题目包含答案且完整,故按要求输出答案及解析...
