Multicast Bandwidth Map Example
The following example creates a multicast bandwidth map for both multicast traffic
admission control and QoS adjustment:
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 using the set admission-bandwidth and set qos-bandwidth
commands.
host1(config)#route-map mcast-bandwidths permit 10
host1(config-route-map)#match ipv6 address sdtv
host1(config-route-map)#set admission-bandwidth 2000000
host1(config-route-map)#set qos-bandwidth 2000000
host1(config-route-map)#route-map mcast-bandwidths permit 20
host1(config-route-map)#match ipv6 address hdtv
host1(config-route-map)#set admission-bandwidth 10000000
host1(config-route-map)#set qos-bandwidth 10000000
host1(config-route-map)#end
2. Define the access list for use by the match ipv6 address command to match (S,G)
and (*,G) entries.
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
host1(config-route-map)#end
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.
For additional information about configuring QoS adjustment, see “Configuring Multicast
QoS Adjustment” on page 151.

see “Blocking and Limiting Multicast Traffic” on page 161.
For additional information about creating route maps, see Configuring Routing Policy in
the JunosE IP Services Configuration Guide .
Configuring Multicast QoS Adjustment
When the router uses multicast OIF mapping, any multicast streams that a subscriber
receives bypass any configured QoS treatment for that subscriber interface. The Multicast
QoS adjust feature provides a way in which the router can account for this multicast
traffic.
