IPMS Overview

Reserved Multicast Addresses

The Internet Assigned Numbers Authority (IANA) created the range for multicast addresses, which is
224.0.0.0 to 239.255.255.255. However, as the table below shows, certain addresses are reserved and
cannot be used.
Address or Address Range
224.0.0.0 through 224.0.0.255
224.0.1.0 through 224.0.1.255
224.0.2.0 through 224.0.255.0
224.1.0.0 through 224.1.255.255
224.2.0.0 through 224.2.255.255
224.252.000.000 through 224.255.255.255
225.000.000.000 through 231.255.255.255
232.000.000.000 through 232.255.255.255
233.000.000.000 through 233.255.255.255

239.000.000.000 through 239.255.255.255

IPMS and Link Aggregation

When configuring IPMS and link aggregation on the same switch the following conditions should be kept
in mind:
When a port moves to a link aggregation group all IPMS configurations on the port will be lost.
•
When the last port in a link aggregation group moves out of the group all IPMS configuration on the
•
link aggregation group will be lost.
