Chapter 44 Configuring IP Multicast Routing
Configuring Basic DVMRP Interoperability Features
Beginning in privileged EXEC mode, follow these steps to set up an administratively-scoped boundary.
This procedure is optional.
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 gigabitethernet1/0/1
Switch(config-if)#
ip multicast boundary 1

Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
access-list
access-list-number
{
deny
|
permit
}
source
[
source-wildcard
]
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.
Step 3
interface
interface-id
Specify the interface to be configured, and enter interface configuration
mode.
Step 4
ip multicast boundary
access-list-number
Configure the boundary, specifying the access list you created in Step 2.
Step 5
end
Return to privileged EXEC mode.
Step 6
show running-config
Verify your entries.
Step 7
copy running-config startup-config
(Optional) Save your entries in the configuration file.
