Configuring Basic Dvmrp Interoperability Features - Cisco Catalyst 3550 series Software Configuration Manual

Chapter 34 Configuring IP Multicast Routing
Beginning in privileged EXEC mode, follow these steps to set up an administratively-scoped boundary:
Command
Step 1
configure terminal
Step 2
access-list access-list-number {deny |
permit} source [source-wildcard]
Step 3
interface interface-id
Step 4
ip multicast boundary
access-list-number
Step 5 end
Step 6 show running-config
Step 7
copy running-config startup-config
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

Purpose
Enter global configuration mode.
Create a standard access list, repeating the command as many times as
necessary.
• For access-list-number, the range is 1 to 99.
• The deny keyword denies access if the conditions are matched. The
permit keyword permits access if the conditions are matched.
• For source, enter the number of the network or host from which the
packet is being sent.
• (Optional) For source-wildcard, enter the wildcard bits in dotted
decimal notation to be applied to the source. Place ones in the bit
positions that you want to ignore.
Recall that the access list is always terminated by an implicit deny
statement for everything.
Enter interface configuration mode, and specify the interface to be
configured.
Configure the boundary, specifying the access list you created in Step 2.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
