Configuring Sparse Mode with Auto-RP
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,
• All access lists that are needed when Auto-RP is configured should be configured prior to beginning the
• If a group has no known RP and the interface is configured to be sparse-dense mode, the interface
Note
• When configuring Auto-RP, you must either configure the Auto-RP listener feature (Step 5) and
• When you configure sparse-dense mode, dense mode failover may result in a network dense-mode
Follow this procedure to configure auto-rendezvous point (Auto-RP). Auto-RP can also be optionally used
with anycast RP.
