IGMP Profile Configuration Mode Commands

The Internet Group Management Protocol (IGMP) Profile Configuration Mode is used to create and manage the IGMP parameters for an Ethernet interface.

IMPORTANT:

Available commands or keywords/variables vary based on platform type, product version, and installed license(s).

default ip igmp

Configures default IGMP parameters.

Platform:

ASR 5000

Product:

All


Privilege:

Security Administrator, Administrator


Syntax
default ip igmp { query | require | robustness | unsolicited-report-interval | version }

Usage:

Specify the IGMP parameters for the default profile. Refer to the remaining command description in this chapter for additional information.


Example:
To apply enable echo mode on this interface, use the following command:
bfd echo 
ip igmp query

Configures the maximum response time for IGMP queries.

Platform:

ASR 5000

Product:

All


Privilege:

Security Administrator, Administrator


Syntax
ip igmp query max-response-time seconds

max-response-time seconds:

Specify the maximum number of seconds that the system will wait for an IGMP response as an integer from 1 through 25.


Usage:

Specify the maximum response time for IGMP queries.


Example:
ip igmp query max-response-time 10 
ip igmp require router-alert

Sets the router alert flag to ON in IP IGMP packets.

Platform:

ASR 5000

Product:

All


Privilege:

Security Administrator, Administrator


Syntax
[ no ] ip
igmp require router-alert

Sets the router alert flag to OFF in IP IGMP packets.


Usage:

Sets the router alert flag to ON in IP IGMP packets.


Example:
ip igmp require router-alert 
ip igmp robustness

Sets the Robustness value in IP IGMP packets. The Robustness variable allows tuning for the expected packet loss on a subnet. If a subnet is expected to be lossy, the Robustness variable may be increased. IGMP is robust to packet losses. The Robustness variable should not be set to 1 (one).

Platform:

ASR 5000

Product:

All


Privilege:

Security Administrator, Administrator


Syntax
ip igmp robustness value

Sets the robustness value as an integer from 1 through 10. Default: 2


Usage:

Sets the robustness value in IP IGMP packets.


Example:
ip igmp robustness
7 
ip igmp unsolicited-report-interval

Sets the Unsolicited Report Interval which is the time between repetitions of a host's initial report of membership in a group.

Platform:

ASR 5000

Product:

All


Privilege:
