Enabling Igmp On An Interface - Juniper JUNOSE 11.0.X MULTICAST ROUTING Configuration Manual

JUNOSe 11.0.x Multicast Routing Configuration Guide
Table 5: IGMP Commands (continued)
The following sections describe the tasks associated with these and other ip igmp
commands.
You can also use various IGMP-specific RADIUS attributes in RADIUS Access-Accept
messages as an alternative method of configuring certain values. See Configuring
RADIUS Attributes in the JUNOSe Broadband Access Configuration Guide for additional
information.

Enabling IGMP on an Interface

You must start IGMP on each interface that you want to use the protocol. You can
configure IGMP and either PIM or DVMRP on the same interface. If you configure
only IGMP on an interface, IGMP owns that interface. If you configure IGMP and
either PIM or DVMRP on an interface, PIM or DVMRP owns the interface.
By enabling IGMP, the router processes incoming multicast packets and creates an
entry in the multicast routing table. If neither PIM nor DVMRP own the interface (for
example, when only IGMP is configured), then the packets are locally routed to other
interfaces on the router. PIM or DVMRP must be configured on the interface for
packets to be sent to other routers.
For networks that use only IGMPv1, you can configure an interface to operate in
IGMPv1 mode. However, IGMPv2 and IGMPv3 interfaces support IGMPv1 hosts. In
an IGMPv1 network, you must configure one interface to act as a querier. In an
IGMPv2 or IGMPv3 network, the querier is the router with the lowest IP address.
To start IGMP, complete the following steps:
1.
2.
3.
ip igmp

Enabling IGMP on an Interface

ip igmp last-member-query-interval
ip igmp promiscuous
ip igmp querier
ip igmp querier-timeout
Enable IGMP on the interface (IGMPv2 is the default version).
(IGMPv1 or IGMPv3) Specify the IGMP version for the interface.
(IGMPv1 only) Specify that the interface act as the querier for the network.
Use to enable IGMP on an interface and to set the IGMP version to IGMPv2. Use
the ip igmp version command to specify a different IGMP version.
Example
host1:boston(config-if)#ip igmp
ip igmp static-include
ip igmp version
