Enabling Installation Of Directly Connected Subnets; Enabling Netflow-Based Rate Limiting Of Rpf Failures - Cisco 6500 Series Software Configuration Manual

Configuring IP Multicast Layer 3 Switching
This example shows how to configure the Layer 3 switching threshold to 10 packets per second:
Router(config)# mls ip multicast threshold 10
Router(config)#

Enabling Installation of Directly Connected Subnets

In PIM sparse mode, a first-hop router that is the designated router for the interface may need to
encapsulate the source traffic in a PIM register message and unicast it to the rendezvous point. To prevent
new sources for the group from being learned in the routing table, the (*,G) flows should remain as
completely hardware-switched flows. (subnet/mask, 224/4) entries installed in the hardware FIB allows
both (*,G) flows to remain completely hardware-switched flows, and new, directly connected sources to
be learned correctly. Installing of directly connected subnets is enabled globally by default. One
(subnet/mask, 224/4) is installed per PIM-enabled interface.
To view FIB entries, enter the show mls ip multicast connected command.
To enable installation of directly connected subnets, perform this task:
Command
Router(config)# mls ip multicast connected
Router(config)# no mls ip multicast connected
This example shows how to enable installation of directly connected subnets:
Router(config)# mls ip multicast connected
Router(config)#

Enabling NetFlow-Based Rate Limiting of RPF Failures

You can enable NetFlow-based rate limiting of RPF failures globally and on a per-Layer 3 interface
basis. When enabled on a global level, the feature is automatically enabled on all eligible Layer 3
interfaces.
To enable NetFlow-based rate limiting of RPF failures on a PFC2, you must first disable CEF-based rate
Note
limiting of RPF failures, which is enabled by default.
To enable NetFlow-based rate limiting of RPF failures, perform this task:
Command
Step 1
Router(config)# mls ip multicast non-rpf netflow
Router(config)# no mls ip multicast non-rpf
netflow
Step 2
Router(config)# interface {{vlan vlan_ID} |
1
{type slot/port} | {port-channel channel_ID}}
