Introduction

Multicast-Routing in IPv6 environment is explicitly enabeled in Global Configuration mode by command "ipv6 multicast-routing". The effect of this command is seen on all IPv6-enabled interfaces on the router which are then automatically enabled also for PIMv6. As this is the default configuration of each interface, the ipv6 pim command is assumed and does not appear in the interface configuration.  When PIMv6 is enabled on an interface, the 

interface always operates in sparse mode. PIM-SM (Sparse-Mode) uses unicast routing to provide reverse-path information for multicast tree building, but it is not dependent on any particular unicast routing protocol.


Note: To disable PIM on a particular interface, command used is "no ipv6 pim" (interface level).

Background

In this document, Router R1, R2 and R3 are enabled with PIM-SM (Sparse Mode), command "ipv6 multicast-routing". . They are also configured with IPv6 OSPF unicast routing. A multicast group is created on R1 and is configured to be a respondent for this group by interface level command "ipv6 mld join-group FF08::10". We are configuring Router R3 to be the Rendezvous Point for this group.


Note: All configuration is tested on Cisco 7200 Series Router running on IOS Version  15.1(3)S3 Advance IP Services Image.

I'm setting MLD in client network


rp-address is my server stream address


i just config like that.. but my video stream with multicast can't forwarding?


can you help me
