Use this command to display information about multicast groups that IGMP proxy reported. This command displays a summary of the host interface status parameters. Use this command from the Interface mode. To enable IGMP Proxy on the router no multicast routing protocol should be enabled and also multicast forwarding must be enabled on the router. The proxy creates the forwarding entries based on the membership information and adds it to the multicast forwarding cache MFC in order not to make the forwarding decision for subsequent multicast packets with same combination of source and group. The router has to decide about forwarding packets on each of its interfaces based on the IGMP membership information. The proxy contains many downstream interfaces and a unique upstream interface explicitly configured. The purpose of IGMP proxy is to enable a multicast router to learn multicast group membership information and be able to forward multicast packets based upon the group membership information. For the type and number arguments, specify the interface to be used as the UDL on the upstream device.This chapter contains the following topics. Note Because PIM messages are not forwarded upstream, each downstream network and the upstream network have a separate domain. Router A creates and maintains a forwarding entry on the unidirectional link UDL. In this scenario, the following sequence of events occurs: User 1 sends an IGMP membership report requesting interest in group G. In this scenario, the following sequence of events occurs: User 2 sends an IGMP membership report requesting interest in group G. Use PIM-DM with the proxy-register capability when the interface is receiving source traffic from a dense-mode region that needs to reach receivers that are in a sparse-mode region. IP multicast is enabled and the PIM interfaces are configured.

PDF - Complete Book Updated: February 17, If all devices on the UDL cannot have the same subnet address, the upstream device must be configured with secondary addresses to match all of the subnets to which the downstream devices are attached. The following commands were introduced or modified: ip igmp helper-addressip igmp mroute-proxyip igmp proxy-serviceip igmp unidirectional-link. IGMP proxy enables hosts in a unidirectional link routing UDLR environment that are not directly connected to a downstream router to join a multicast group sourced from an upstream network.

No new or modified MIBs are supported by this feature, and support for existing standards has not been modified by this feature. The ip igmp proxy-service command is intended to be used with the ip igmp helper-address UDL command. Because PIM messages are not forwarded upstream, each downstream network and the upstream network have a separate domain. With unidirectional link routing UDLR alone, scenario 2 would not be possible because receiving hosts must be directly connected to the downstream device, Router B. In an enterprise network, it is desirable to be able to receive IP multicast traffic via satellite and forward the traffic throughout the network. For scenario 2, the IGMP proxy mechanism is needed to enable hosts that are not directly connected to a downstream device to join a multicast group sourced from an upstream network. In this scenario, the following sequence of events occurs. For scenario 1, no IGMP proxy mechanism is needed.
