SROS Command Line Interface Reference Guide Global Configuration Mode Command Set
ip igmp join <group-address>
Use the ip igmp join command to instruct the router stack to join a specific group. The stack may join
multiple groups.
Syntax Description
<group-address> IP address of a multicast group.
Default Values
No defaults necessary for this command.
Functional Notes
This command aids in debugging, allowing the router's IP stack to connect to and respond on a multicast
group. The local stack operates as an IGMP host on the attached segment. In multicast stub applications,
the global helper address takes care of forwarding IGMP joins/responses on the upstream interface. The
router may respond to ICMP echo requests for the joined groups.
Usage Examples
The following example configures the unit to join with the specified multicast group:
ProCurve(config)#ip igmp join 172.0.1.50
