Configuring IP Multicast Layer 3 Switching
This example shows how to enable NetFlow-based rate limiting of non-RPF failures globally:
Router(config)# mls ip multicast non-rpf netflow
Router(config)#
Enabling CEF-Based Rate Limiting of RPF Failures
CEF-based rate limiting of RPF failures is enabled by default on systems with PFC2. CEF-based rate
limiting of RPF failures can be configured globally only.
To enable CEF-based rate limiting of RPF failures, perform this task:
This example shows how to enable CEF-based rate limiting of RPF failures globally:
Router(config)# mls ip multicast non-rpf CEF
Router(config)#
Enabling Shortcut-Consistency Checking
When you enable the shortcut-consistency checking feature, the multicast route table and the
multicast-hardware entries are are checked for consistency, and any inconsistencies are corrected. You
can view inconsistencies by entering the show mls ip multicast consistency-check command.
If consistency checking is enabled, the multicast route table will be scanned every two seconds and a full
scan is completed within 4 mintues.
To enable shortcut-consistency checking, perform this task:
Step 3
Router(config-if)# mls ip multicast non-rpf
netflow
Enables NetFlow-based rate limiting of RPF failures on
the Layer 3 interface.
Router(config-if)# no mls ip multicast non-rpf
netflow
Disables NetFlow-based rate limiting of RPF failures on
the Layer 3 interface.
