Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command configures a static multicast route on the public network.

source-address: Specifies a multicast source address.

mask-length: Specifies an address mask length in the range of 0 to 32.

mask: Specifies an address mask.

rpf-nbr-address: Specifies an RPF neighbor by its IP address.

interface-type interface-number: Specifies an interface by its type and number. The interface connects the RPF neighbor.

preference: Specifies a route preference in the range of 1 to 255. The default value is 1.

Usage guidelines

In the same multicast source address range, you can configure up to 16 RPF neighbors.

When you specify an RPF neighbor, follow these guidelines:

· If the RPF neighbor is a point-to-point interface, you must specify the type and number of the interface.

· If the RPF neighbor is not a point-to-point interface, you must specify the IP address of the interface. This type of interfaces includes Layer 3 Ethernet, Layer 3 aggregate, Loopback, and VLAN interfaces.

The configured static multicast route might not take effect when one of the following conditions exists:

· The outgoing interface iteration fails.

· The specified interface is not in the public network or the same VPN instance as the current interface.

· The specified interface is not a point-to-point interface.

· The specified interface is down.

If multiple static multicast routes within the same multicast source address range are available, only the one with the highest route preference can become active. You can use the display multicast routing-table static command to verify that the configured static multicast route has taken effect.

The undo ip rpf-route-static command deletes the specified static multicast route. To delete all static multicast routes, use the delete ip rpf-route-static command.

Examples

# On the public network, configure a static multicast route to multicast source 10.1.1.1/24, and specify the interface with IP address 192.168.1.23 as its RPF neighbor.

mac-address: Specifies a static multicast MAC address, in the format H-H-H. The multicast MAC address must be an unused one. A multicast MAC address is a MAC address in which the least significant bit of the most significant octet is 1.

interface interface-list: Specifies a space-separated list of up to four interface items. Each item specifies an interface or an interface list in the format of start-interface-type interface-number to end-interface-type interface-number. The interface-type interface-number argument specifies an interface by its type and number. The available interface types include Layer 2 Ethernet interfaces and Layer 2 aggregate interfaces.

vlan vlan-id: Specifies a VLAN by its VLAN ID in the range of 1 to 4094. The specified VLAN must exist, and the system gives a prompt if the specified interface does not belong to the VLAN.

Usage guidelines

You can configure static multicast MAC address entries for the specified interface in system view or for the current interface in interface view.

If you do not specify the multicast keyword, the undo mac-address command deletes all MAC address entries, including static unicast and multicast MAC address entries.

Examples

# Create a static multicast MAC entry for 0100-0001-0001 in VLAN 2. In this entry, Ten-GigabitEthernet 1/1/1 through Ten-GigabitEthernet 1/1/5 in VLAN 2 are outgoing ports.

<Sysname> system-view

[Sysname] mac-address multicast 0100-0001-0001 interface ten-gigabitethernet 1/1/1 to ten-gigabitethernet 1/1/5 vlan 2

# Configure a static multicast MAC entry for 0100-0001-0001 on Ten-GigabitEthernet 1/1/1 in VLAN 2.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 1/1/1

[Sysname-Ten-GigabitEthernet1/1/1] mac-address multicast 0100-0001-0001 vlan 2

multicast boundary

Use multicast boundary to configure a multicast forwarding boundary.

Use undo multicast boundary to remove a multicast forwarding boundary.

Syntax

multicast boundary group-address { mask-length | mask }

undo multicast boundary { group-address { mask-length | mask } | all }

Default

An interface is not a multicast forwarding boundary.

Views

network-admin

Parameters

group-address: Specifies a multicast group address in the range of 224.0.0.0 to 239.255.255.255.

mask-length: Specifies an address mask length in the range of 4 to 32.

mask: Specifies an address mask.

all: Specifies all forwarding boundaries configured on the interface.

Usage guidelines

A multicast forwarding boundary sets the boundary condition for the multicast groups in the specified address range. If the destination address of a multicast packet matches the set boundary condition, the packet is not forwarded.

An interface can act as a forwarding boundary for multiple multicast groups in different address ranges. To achieve this, use this command on the interface for each multicast address range.

Assume that Set A and Set B are multicast forwarding boundary sets with different address ranges, and B is a subset of A. A takes effect on the interface no matter whether A is configured earlier or later than B.

Examples

# Configure VLAN-interface 100 as the forwarding boundary of multicast groups in the range of 239.2.0.0/16.

<Sysname> system-view

[Sysname] interface vlan-interface 100

[Sysname-Vlan-interface100] multicast boundary 239.2.0.0 16

multicast forwarding supervlan community

Use multicast forwarding supervlan community to enable multicast forwarding between sub-VLANs that are associated with a super VLAN.

Use undo multicast forwarding supervlan community to disable multicast forwarding between sub-VLANs that are associated with a super VLAN..

Syntax

multicast forwarding supervlan community

undo multicast forwarding supervlan community

Default

Multicast data cannot be forwarded between sub-VLANs that are associated with a super VLAN.

Views

VLAN interface view

Predefined user roles

network-admin

Usage guidelines

After you execute the multicast forwarding supervlan community command, you must clear all multicast forwarding entries with the super VLAN interface as the incoming interface. Otherwise, this command cannot take effect. To clear the required multicast forwarding entries, use the reset multicast forwarding-table command.

Examples

# Enable multicast forwarding between sub-VLANs that are associated with super VLAN 2.

<Sysname> system-view

[Sysname] interface vlan-interface 2

[Sysname-Vlan-interface2] multicast forwarding supervlan community

multicast routing

Use multicast routing to enable IP multicast routing and enter MRIB view.

Use undo multicast routing to disable IP multicast routing.

Syntax

multicast routing [ vpn-instance vpn-instance-name ]

undo multicast routing [ vpn-instance vpn-instance-name ]

Default

IP multicast routing is disabled.

Views

System view

network-admin

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command enables IP multicast routing on the public network.

Usage guidelines

Other Layer 3 multicast commands take effect only when IP multicast routing is enabled.

The switch does not forward multicast packets before IP multicast routing is enabled.

Examples

# Enable IP multicast routing and enter MRIB view on the public network.

<Sysname> system-view

[Sysname] multicast routing

[Sysname-mrib]

# Enable IP multicast routing and enter MRIB view in VPN instance mvpn.

<Sysname> system-view
