Table 5: IGMP Commands
(continued)
ip igmp static-include
ip igmp last-member-query-interval
ip igmp version
ip igmp promiscuous
multicast group port limit
ip igmp querier
ip igmp querier-timeout
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.
Enable IGMP on the interface (IGMPv2 is the default version).
2.
(IGMPv1 or IGMPv3) Specify the IGMP version for the interface.
3.
(IGMPv1 only) Specify that the interface act as the querier for the network.
ip igmp
■
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.
