Adding DSG Tunnel Group to a Subinterface
This procedure adds a DSG tunnel group to a subinterface using the cable dsg tg group-id command. After
adding the DSG tunnel-group to a subinterface, appropriate IP Internet Group Management Protocol (IGMP)
static joins are created and forwarding of DSG traffic begins, if the downstream DSG is configured.
Before You Begin
The downstream DSG should exist to create IGMP static joins.
You can associate a DSG tunnel group to only one subinterface within the same bundle interface.Restriction
