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 deletes all static multicast routes on the public network.

Usage guidelines

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

Examples

# Delete all static multicast routes on the public network.

<Sysname> system-view

[Sysname] delete ip rpf-route-static

This will erase all multicast static routes and their configurations, you must reconfigure all static routes.

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

Usage guidelines

If the interface connected to an RPF neighbor is a point-to-point interface, you must specify the interface by its type and number.

If the interface connected to an RPF neighbor is not a point-to-point interface, you must specify the interface by its IP address. 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, but the delete ip rpf-route-static command deletes all static multicast routes.

Examples

# Configure a static multicast route to multicast source 10.1.1.0/24 and specify the interface with IP address 192.168.1.23 as the RPF neighbor on the public network.

<Sysname> system-view

[Sysname] ip rpf-route-static 10.1.1.0 24 192.168.1.23

Parameters

source: Enables multicast load splitting based on multicast source.

source-group: Enables multicast load splitting based on multicast source and group.

Usage guidelines

This command does not take effect on BIDIR-PIM.

longest-match (MRIB view)

Use longest-match to specify the longest prefix match principle for RPF route.

Use undo longest-match to restore the default.

Syntax

longest-match

undo longest-match

Default

Route preference is used for RPF route selection. The route with the highest preference is used as the RPF route.

Views

MRIB view

Predefined user roles

network-admin

Usage guidelines

This command enables the device to use the matching route with the longest prefix as the RPF route.

Examples

# Specify the longest prefix match principle for RPF route selection on the public network.

multicast boundary

Use multicast boundary to configure a multicast forwarding boundary.

Use undo multicast boundary to delete a multicast forwarding boundary.

Syntax

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

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

Default

No multicast forwarding boundaries are configured on an interface.

Views

Predefined user roles

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.

You can configure an interface as a multicast forwarding boundary for different multicast group ranges by executing this command multiple times on the interface.

You do not need to enable IP multicast routing before you execute this command.

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 GigabitEthernet 1/0 as the forwarding boundary of multicast groups in the range of 239.2.0.0/16.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0

[Sysname-GigabitEthernet1/0] multicast boundary 239.2.0.0 16

Default

The device can cache only one unknown multicast packet for an (S, G) entry.

Views

network-admin

Parameters

per-entry-limit: Specifies the maximum number of unknown multicast packets that can be cached for an (S, G) entry. The value range for this argument is 0 to 256. If you set the value to 0, the device cannot cache unknown multicast packets.

Examples

# Set the maximum number to 20 for unknown multicast packets that can be cached for an (S, G) entry.

Parameters

total-limit: Specifies the maximum number of all unknown multicast packets that can be cached. The value range for this argument is 0 to 65535. If you set the value to 0, the device cannot cache unknown multicast packets.

Usage guidelines

As a best practice, set the value in this command to be far greater than the value set in the multicast forwarding-table cache-unknown per-entry command.

Examples

# Set the maximum number to 10000 for all unknown multicast packets that can be cached.

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

Before you execute this command, complete the following tasks:

· Enable the device to flood the multicast data packets that fail the RPF check in all VLANs.

· Enable IGMP snooping for the current VLAN.

For this command to take effect, you must clear dynamic IGMP snooping forwarding entries in the VLAN after executing this command. To clear dynamic IGMP snooping forwarding entries, use the reset igmp-snooping group command.

You do not need to enable IP multicast routing before you execute this command.
