Cisco CPT Command Reference Guide–CTC and Documentation Release 9.3 and Cisco IOS Release 15.1(01)SA - MVR Command Reference [Cisco Carrier Packet Transport (CPT) System]

mvr

To enable Multicast VLAN Registration (MVR), use the mvr command in the bridge domain configuration mode. To disable MVR, use the no form of this command.

mvr

no mvr

Syntax Description

This command has no arguments or keywords.

Command Default

MVR is not enabled.

Command Modes

Bridge domain configuration (config-bdomain)

Command History

Release	Modification
9.3.0	This command was introduced.

Usage Guidelines

On a CPT system, MVR can be configured at the bridge domain level.

Following configuration restrictions are applicable while configuring the MVR on the CPT system:

For a single tagged packet, the tag is removed using the rewrite ingress tag pop 1 symmetric command at the EFP level.
For a double tagged packet, the tag is removed using the rewrite ingress tag pop 2 symmetric command at the EFP level.
For an untagged packet, a rewrite operation is not required.

Examples

The following example shows how to enable MVR on bridge domain 22 and configure the group address.

Router(config)# bridge-domain 22
Router(config-bdomain)# mvr
Router(config-bdomain)# mvr group 228.1.23.4 5
Router(config-bdomain)# end

Related Commands

Command	Description
show mvr	Verifies the MVR configuration.

mvr group

To define a global range of IP multicast groups on which MVR must be enabled, use the mvr group command in the bridge domain configuration mode. To remove the IP multicast address groups, use the no form of this command.

mvr group ip-address [count]

no mvr group ip-address [count]

Syntax Description

ip-address	Group IP address.
count	Group count inside the bridge domain.

Command Default

The IP multicast address on which the MVR feature must be enabled is not defined.

Command Modes

Bridge domain configuration (config-bdomain)

Command History

9.3.0	This command was introduced.

Usage Guidelines

On a CPT system, MVR can be configured at the bridge domain level.

Following configuration restrictions are applicable while configuring the MVR on the CPT system:

For a single tagged packet, the tag is removed using the rewrite ingress tag pop 1 symmetric command at the EFP level.
For a double tagged packet, the tag is removed using the rewrite ingress tag pop 2 symmetric command at the EFP level.
For an untagged packet, a rewrite operation is not required.

The mvr group ip-address [count] command configures an IP multicast address on the CPT system. The optional count parameter is used to configure a contiguous series of MVR group addresses (the range for count is from 1 to 2000; the default is 1). Any multicast data sent to the IP address mentioned in the command is sent to all source EFPs on the CPT system and all receiver EFPs that have elected to receive data on that multicast address. The no form of the deletes the multicast IP address configuration.

Examples

The following example shows how to enable MVR on bridge domain 22 and configure the group address.

Router(config)# bridge-domain 22
Router(config-bdomain)# mvr
Router(config-bdomain)# mvr group 228.1.23.4 5
Router(config-bdomain)# end

Command	Description
show mvr	Displays the MVR configuration.
show mvr groups	Displays the group MVR configuration.

mvr type

To configure an EFP as the MVR enabled source or receiver, use the mvr type command in the service-instance mode. To remove the source or receiver port configuration, use the no form of this command.

mvr type {source | receiver bridge-domain id [vlan id] [immediate]}

no mvr type {source | receiver bridge-domain id [vlan id] [immediate]}

Syntax Description

source	Configures an MVR EFP as the source.
receiver bridge-domain id	Configures an MVR EFP as the receiver. id —Bridge domain ID.
vlan id	(Optional) Specifies the VLAN ID to be used when the VLAN range is mentioned. This option is used only on the receiver EFP. id —VLAN ID.
immediate	(Optional) Enables the Immediate-Leave feature on the receiver EFP.

Command Default

There is no default setting for this command.

Command Modes

Service instance mode (config-if-srv)

Command History

Release	Modification
9.3.0	This command was introduced.

Usage Guidelines

Users must configure an MVR bridge domain before configuring the MVR source and receiver EFPs.

An MVR enabled EFP (subscriber port) is configured as the receiver to receive only multicast data. It does not receive data unless it becomes a member of the multicast group, either statically or by using IGMP leave and join messages. Receiver EFPs cannot belong to the multicast bridge-domain.

The mvr type {source | receiver bridge-domain id [vlan id] [immediate]} command is used to configure the EFPs, where bridge-domain id [vlan id] [immediate] is only applicable to the receiver EFPs.

Examples

This example shows how to enable MVR on the bridge domains and configure source MVR EFPs and receiver MVR EFPs.
