Chapter34 Configuring IP Multicast Routing
Monitoring and Maintaining IP Multicas t Routing
To remove the boundary, use the no ip multicast boundary interface configuration command.
This example shows how to set up a boundary for all administratively-scoped addresses:
Switch(config)# access-list 1 deny 239.0.0.0 0.255.255.255
Switch(config)# access-list 1 permit 224.0.0.0 15.255.255.255
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# ip multicast boundary 1
