3 Configuring the Switch CLI - This example configures profile number 19 by setting the access mode to "permit" and then specifying a range of multicast groups that a user can join. The current profile configuration is then displayed. Console(config)#ip igmp profile 19 Console(config-igmp-profile)#permit Console(config-igmp-profile)#range 239.1.1.1 Console(config-igmp-profile)#range 239.2.3.1 239.2.3.100 Console(config-igmp-profile)#end Console#show ip igmp profile 19 IGMP Profile 19 permit range 239.1.1.1 239.1.1.1 range 239.2.3.1 239.2.3.100 Console# 4-222 4-222 4-223 4-226 Multicast VLAN Registration Multicast VLAN Registration (MVR) is a protocol that controls access to a single network-wide VLAN most commonly used for transmitting multicast traffic (such as television channels or video-on-demand) across a service provider's network. Any multicast traffic entering an MVR VLAN is sent to all attached subscribers. This protocol can significantly reduce to processing overhead required to dynamically monitor and establish the distribution tree for a normal multicast VLAN. This makes it possible to support common multicast services over a wide part of the network without having to use any multicast routing protocol. MVR maintains the user isolation and data security provided by VLAN segregation by passing only multicast traffic into other VLANs to which the subscribers belong. Even though common multicast streams are passed onto different VLAN groups from the MVR VLAN, users in different IEEE 802.1Q or private VLANs cannot exchange any information (except through upper-level routing services). 3-174
