Configuring IPv6 Multicast-Routing

Overview

Function Introduction

Multicast protocols allow a group or channel to be accessed over different networks by multiple stations (clients) for the receipt and transmit of multicast data.

Distribution of stock quotes, video transmissions such as news services and remote classrooms, and video conferencing are all examples of applications that use multicast routing.

  • Mulitcast Listener Discovery (MLD) is used among hosts on a LAN and the routers (and multilayer switches) on that LAN to track the multicast groups of which hosts are members.

  • Protocol-Independent Multicast (PIM) protocol is used among routers and multilayer switches to track which multicast packets to forward to each other and to their directly connected LANs. PIM has two modes: Sparse-mode and Dense-mode. Currently, we only support Sparse-mode

Configuration

Configuring IPv6 multicast route limit

step 1 Enter the configure mode

Switch# configure terminal

step 2 Set the limit of the IPv6 multicast route

Switch(config)# ipv6 multicast route-limit 1000

step 3 Exit the configure mode

Switch(config)# end

step 4 Validation

Switch show ipv6 mroute route-limit
IPv6 Max Multicast Route Limit Number: 1000
IPv6 Multicast Route Limit Warning Threshold: 1000
IPv6 Multicast Hardware Route Limit: 255
IPv6 Current Multicast Route Entry Number: 0
