Prerequisites for IGMP Snooping
The following prerequisites must be satisfied before implementing IGMP snooping:
-
The network must be configured with a Layer 2 VPN (L2VPN).
-
You must be in a user group associated with a task group that includes the proper task IDs. The command reference guides include the task IDs required for each command. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
