Configuring MLS
Enabling IP PIM on MSFC Interfaces
You must enable IP PIM on the MSFC interfaces before IP MMLS will function on those interfaces.
To enable IP PIM on an interface, perform this task:
Task
Enable IP PIM on an MSFC interface. Router(config-if)# ip pim {dense-mode | sparse-mode |
This example shows how to enable IP PIM on an interface using the default mode (sparse-dense-mode):
Router(config-if)# ip pim
Router(config-if)#
This example shows how to enable IP PIM sparse mode on an interface:
Router(config-if)# ip pim sparse-mode
Router(config-if)#
Configuring the IP MMLS Global Threshold
You can configure a global multicast rate threshold, which is specified in packets per second, below
which all (S,G) multicast traffic is routed by the MSFC. Entering the command prevents the creation of
MLS entries for short-lived multicast flows (such as join requests).
This command does not affect the flows that are already being routed. To apply the threshold to existing
Note
routes, clear the route and let it reestablish.
To configure the IP MMLS threshold, perform this task:
Task
Configure the IP MMLS threshold.
This example shows how to configure the IP MMLS threshold to 10 packets per second:
Router(config)# mls ip multicast threshold 10
Router(config)#
Use the no keyword to deconfigure the threshold.
Enabling IP MMLS on MSFC Interfaces
IP MMLS is enabled by default on the MSFC interface when you enable IP PIM on the interface. Perform
this task only if you disabled IP MMLS on the interface and you want to reenable it.
You must enable IP PIM on all the participating MSFC interfaces before IP MMLS will function. For
