ip igmp robustness
11-16 IGMP Configuration
Example
This example shows how to set the IGMP last member query count to 10 on VLAN 1:
C2(su)->router(Config)#interface vlan 1
C2(su)->router(Config-if(Vlan 1))#ip igmp last-member-query-count 10
ip igmp robustness
Use this command to configure the robustness tuning for expected packet loss on an IGMP
routing interface. The no form of this command resets the IGMP robustness value to the default of
2.
Syntax
ip igmp robustness robustness
no ip igmp robustness
Parameters
Defaults
None.
Mode
Interface configuration: C2 (su) ‐ >router(Config ‐ if(Vlan 1))#
Usage
This value determines how many times IGMP messages will be sent. A higher number will mean
that end stations will be more likely to see the packet. After the robustness value is reached, IGMP
will assume there is no response to queries.
Example
This example shows how to set the IGMP robustness value to 5 on VLAN 1:
C2(su)->router(Config)#interface vlan 1
C2(su)->router(Config-if(Vlan 1))#ip igmp robustness 5
robustness Specifies the IGMP robustness value. Valid values are from 1 to 255 . The
default value is 2.
