ip igmp
Use the ip igmp command to configure multicasting related functions for the interface. Variations of this
command include:
ip igmp immediate-leave
ip igmp last-member-query-interval <milliseconds>
ip igmp querier-timeout <seconds>
ip igmp query-interval <seconds>
ip igmp query-max-response-time <seconds>
ip igmp static-group <address>
ip igmp version [1 | 2]
Syntax Description
immediate-leave
last-member-query-interval
<milliseconds>
querier-timeout <seconds>
query-interval <seconds>
query-max-response-time
<seconds>
60000CRG0-35E
Specifies that if only one host (or Internet Group Management Protocol
(IGMP) snooping switch) is connected to the interface, when a leave is
received, multicast of that group is immediately terminated as opposed
to sending a group query and timing out the group if no device responds.
Works in conjunction with ip igmp last-member-query-interval.
Applies to all groups when configured. Use the no form of this command
to disable the immediate-leave feature.
Controls the timeout (in milliseconds) used to detect whether any group
receivers remain on an interface after a receiver leaves a group. If a
receiver sends a leave-group message (IGMP Version 2), the router
sends a group-specific query on that interface. After twice the time
specified by this command plus as much as one second longer, if no
receiver responds, the router removes that interface from the group and
stops sending that group's multicast packets to the interface. Range is
100 to 65535 ms. Use the no form of this command to return to the
default setting.
Specifies the interval (in seconds) that the router waits after the current
querier's last query before it takes over as querier (IGMP Version 2).
Range is 60 to 300 seconds. Use the no form of this command to return
to the default setting.
Specifies the interval (in seconds) at which IGMP queries are sent on an
interface. Host query messages are addressed to the all-hosts multicast
group with an IP time to live (TTL) of 1. The router uses queries to detect
whether multicast group members are on the interface and to select an
IGMP designated router (DR) for the attached segment (if more than one
multicast router exists). Only the DR for the segment sends queries. For
IGMP Version 2, the DR is the router with the lowest IP address on the
segment. Range is 0 to 65535 seconds. Use the no form of this
command to return to the default setting.
Specifies the maximum response time (in seconds) advertised by this
interface in queries when using IGMP Version 2. Hosts are allowed a
random time within this period to respond, reducing response bursts.
Use the no form of this command to return to the default setting.
