Example: Configuring an IPv6 Multicast Bandwidth Map

This example shows how to create a multicast bandwidth map for both multicast traffic admission control and QoS adjustment.

Requirements

This example uses the following hardware and software components:

Before you begin configuring multicast on IPv6 interfaces, you must:

Overview

The multicast bandwidth map is a route map that uses the set admission-bandwidth, set qos-bandwidth, set admission-bandwidth adaptive, or set qos-bandwidth adaptive commands. Multicast interface-level admission control, port-level admission control, and QoS adjustment all use a single multicast bandwidth map.

The adaptive commands configure an auto-sense mechanism for measuring the multicast bandwidth.

Configuring an IPv6 Multicast Bandwidth Map

Configuring a Route Map

Step-by-Step Procedure

Define a route map using the set admission-bandwidth and set qos-bandwidth commands.

Note: In this example, you can replace the set admission-bandwidth command and set qos-bandwidth command with their adaptive command counterparts.

  1. Define a route map.
    [edit]host1(config)#route-map mcast-bandwidths permit 10
  2. Match the route map to an access list.
    [edit]host1(config-route-map)#match ipv6 address sdtv
  3. Configure multicast bandwidths.
    [edit multicast bandwidths for admission control and QoS adjustment]host1(config-route-map)#set admission-bandwidth 2000000 host1(config-route-map)#set qos-bandwidth 2000000
  4. Configure the route map.
    [edit]host1(config-route-map)#route-map mcast-bandwidths permit 20
  5. Match the route map to an access list.
    [edit]host1(config-route-map)#match ipv6 address hdtv
  6. Configure multicast bandwidths.
    [edit multicast bandwidths for admission control and QoS adjustment]host1(config-route-map)#set admission-bandwidth 10000000 host1(config-route-map)#set qos-bandwidth 10000000

Configuring an Access List

Step-by-Step Procedure

Define the access list for use by the match ipv6 address command to match (S,G) and (*,G) entries.

Note: You can also define a prefix-list or a prefix-tree for use by the match ipv6 address command to match (S,G) and (*,G) entries.

  1. Configure access lists.
    [edit access lists]host1(config)#access-list sdtv permit ip host 31::1 ff3e::0/112 host1(config)#access-list hdtv permit ip host 32::1 ff3e::0/112 host1(config)#access-list hdtv permit ip host 32::2 ff3e::0/112
