Usage Guidelines
•
IP Multicast Switching and Routing must be enabled to set the IGMP robustness variable on the system
and/or the specified VLANs.
•
If the IGMP robustness variable is already configured on the system, then the VLAN configuration will
override the system's configuration.
•
Robustness variable allows fine-tuning on the network, where the expected packet loss would be
greater.
•
To restore the IGMP robustness variable to its default (i.e., 2) value on the system if no VLAN is spec-
ified, use ip multicast robustness followed by the value 0 (e.g., ip multicast robustness 0) or use only
ip multicast robustness (e.g., ip multicast robustness).
•
To restore the IGMP robustness variable to its default (i.e., 2) value on the specified VLAN, use
ip multicast vlan vid robustness followed by the value 0 (e.g., ip multicast vlan 2 robustness 0) or use
only ip multicast vlan vid robustness (e.g., ip multicast vlan 2 robustness).
Examples
-> ip multicast robustness 3
-> ip multicast robustness 0

-> ip multicast vlan 2 robustness 3
-> ip multicast vlan 2 robustness 0
-> ip multicast vlan 2 robustness
