Chapter 40 Configuring IP Multicast Routing
Monitoring and Maintaining IP Multicast 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
Monitoring and Maintaining IP Multicast Routing
These sections describe how to monitor and maintain IP multicast routing:
• Clearing Caches, Tables, and Databases, page 40-46
• Displaying System and Network Statistics, page 40-46
• Monitoring IP Multicast Routing, page 40-47

might be necessary when the contents of the particular structure are or suspected to be invalid.
You can use any of the privileged EXEC commands in Table 40-6 to clear IP multicast caches, tables,
and databases:
