Application Example for Configuring Multicast
Address Boundaries
This section illustrates multicast address boundary configuration for a simple multicast network. The
network consists of a core switch with a backbone connection to the Internet. The core switch is given a
boundary of 239.0.0.0/8. This is the broadest boundary, keeping all multicast traffic addressed to 239.0.0.0
through 239.255.255.255 from leaving the company network.
The core switch is connected to two wiring closet switches. The wiring closet switches serve the Human
Resources and Training network domains. A boundary of 239.188.0.0/16 is created for both the Human
Resources and Training domains. No multicast traffic within the range of 239.188.0.0 through
239.188.255.255 is permitted to leave either domain. This allows multicast addresses within the range to
be used simultaneously in both domains without conflict.
Note.

1
Verify that either PIM or DVMRP is loaded on the switch. Refer to the “Configuring PIM” or “Config-
uring DVMRP” chapters in the
OmniSwitch AOS Release 7 Advanced Routing Configuration Guide
for
more information.
2
Create a VLAN on the core switch. For example:
-> vlan 2
3
Next, create a IP interface on the VLAN. The IP interface serves as the interface identifier on which the
boundary will be created. To create a IP interface, use the
ip interface
command. For example:
-> ip interface vlan-2 address 178.10.1.1 vlan 2
show ip mroute-boundary
Displays scoped multicast address boundaries for the switch’s router
interfaces.
