Configuring IP Multicast

Configuring IP Multicast

To configure IP multicast over an RFC 1483 permanent virtual connection (PVC) on an ATM router module, use the following commands, beginning in global configuration mode:

	Command	Purpose
Step 1
	Switch(config)# ip multicast-routing	Enables IP multicast routing.
Step 2
	Switch(config)# interface atm	Creates the ATM router module point-to-multipoint
	card/subcard/port.subinterface# multipoint	subinterface, and enters subinterface mode.
	Switch(config-subif)#	Note The ATM router module only supports
		point-to-multipoint subinterfaces.
Step 3
	Switch(config-subif)# map-groupname	Enters the map group name associated with this PVC.
Step 4 Switch(config-subif)# atm pvc 2 vci-a[upc upc]		Configures the PVC.
	[pd pd] interface atm card/subcard/port[.vpt#]	Note The VPI number on the ATM router module
	vpi-bvci-b[upc upc] encap aal5snap
		interface must be 2.
Step 5
	Switch(config-subif)# ip pim dense-mode	Enables Protocol Independent Multicast dense mode
		on the subinterface.
Step 6
	Switch(config-subif)# exit	Returns to global configuration mode.
	Switch(config)#
Step 7
	Switch(config)# map-listname	Creates a map list by naming it, and enters map-list
	Switch(config-map-list)#	configuration mode.
Step 8
	Switch(config-map-list)# ip ip-address	Associates a protocol and address with a specific
	{atm-nsap address atm-vc vci} broadcast	virtual circuit.
Step 9
	Switch(config-map-list)# end	Returns to privileged EXEC mode.
	Switch#
	Example
	Switch(config)# ip multicast-routing
	Switch(config)# interface atm 1/0/0.1011 multipoint
	Switch(config-subif)#ip address 10.1.1.1 255.255.255.0
	Switch(config-subif)# map-group net1011
	Switch(config-subif)#atm pvc 2 1011 interface atm 3/0/0 0 1011 encap aal5snap
	Switch(config-subif)# ip pim dense-mode
	Switch(config-subif)# exit
	Switch(config)# map-list net1011
	Switch(config-map-list)#ip 10.1.1.2 atm-vc 1011 broadcast
Note	For more information on IP multicast, refer to the Layer 3 Software Configuration Guide.

About Rate Limiting

Rate limiting is available on the Catalyst 8540 MSR, Catalyst 8510 MSR, Catalyst 8540 CSR, and Catalyst 8510 CSR. This feature is similar to the IOS committed access rate (CAR) feature. You can deploy rate limiting on your switch router to ensure that a packet, or data source, adheres to a stipulated contract, and to determine the QoS for a packet.
