Cisco Catalyst 3650 User Manual

Configuring Sparse Mode with Auto-RP
Before You Begin
•
An interface configured in sparse-dense mode is treated in either sparse mode or dense mode of operation,
depending on the mode in which the multicast group operates. You must decide how to configure your
interfaces.
•
All access lists that are needed when Auto-RP is configured should be configured prior to beginning the
configuration task.
Note
•
If a group has no known RP and the interface is configured to be sparse-dense mode, the interface
is treated as if it were in dense mode, and data is flooded over the interface. To avoid this data
flooding, configure the Auto-RP listener and then configure the interface as sparse mode.
•
When configuring Auto-RP, you must either configure the Auto-RP listener feature (Step 5) and
specify sparse mode (Step 7) or specify sparse-dense mode (Step 8) .
•
When you configure sparse-dense mode, dense mode failover may result in a network dense-mode
flood. To avoid this condition, use PIM sparse mode with the Auto-RP listener feature.
Follow this procedure to configure auto-rendezvous point (Auto-RP). Auto-RP can also be optionally used
with anycast RP.
