• Interface Name:[ ] – Enter the name of the IP interface that is to be configured for multicasting in this
field. This must be a previously configured IP interface. See Setting up IP Interfaces in Chapter 6 of this
manual for more information.
• IGMP: < > – Toggle between Enabled and Disabled using the space bar. This will enable or disable IGMP
for the IP interface entered above.
• Protocol: < > – Toggle among PIM-DM (Protocol Independent Multicasting – Dense Mode), DVMRP
(Distance Vector Multicasting Routing Protocol), and INACT (inactive). INACT is not a multicast routing
protocol. It is used to make a given interface inactive for multicast routing.
IGMP Interface Configuration
To configure the IGMP interface, highlight IGMP Interface Configuration from the IP Multicasting Settings
menu and press Enter.

• Interface Name:[ ] – Enter the name of the interface in this field. This interface must be previously
defined.
• Querier State:< > – This field can be toggled between V1-Querier and V2-Querier. This is the version of
IGMP that the interface will use (IGMP version 1 or IGMP version 2).
• Query:[ ] – This field allows an entry between 1 and 65,500 seconds and defines the time between
transmitting IGMP queries.
• Max Response:[ ] – This field allows an entry between 1 and 25 and defines the maximum time allowed
before sending a response report to a query. This is used to adjust the “leave latency”, the time internal between
the moment the last host leaves a group and when the routing protocol is notified there are no more members.
