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.

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 traces a multicast path on the public network.

source-address: Specifies a multicast source by its IP address.

group-address: Specifies a multicast group by its IP address, in the range of 224.0.1.0 to 239.255.255.255.

destination address: Specifies the destination address of mtrace. The default destination address is 224.0.0.2.

verbose: Displays detailed information about mtrace. If you do not specify this keyword, the command displays brief information about mtrace.

Usage guidelines

To perform a non-group-specific mtrace, specify a multicast source and a destination. The mtrace starts from the destination and ends at the device directly connected to the multicast source.

To perform a non-source-specific mtrace, specify a multicast group and a destination. The mtrace starts from the destination and ends at the RP associated with the multicast group.

To perform a source-and-group-specific mtrace, specify both a multicast source and a multicast group. If you also specify a destination, the mtrace starts from the destination and ends at the device directly connected to the multicast source. If you do not specify a destination, the mtrace starts from the upstream device of the client and ends at the device directly connected to the multicast source.

An mtrace process stops if the number of traced hops reaches 255.

If the client does not receive a Reply message within 10 seconds, the client initiates a hop-by-hop mtrace to determine which device on the path encountered an error. It sends a Query message with the hops field set to 1 and waits for a Reply message. If it does not receive a Reply message within 10 seconds, the client determines that this hop encountered an error. If the client receives a Reply message within 10 seconds, it sends a Query message with the hops field value increased by 1 and waits for a Reply message. This process continues until the client does not receive a Reply message within the waiting time any more.

Examples

# Use mtrace1 to trace the path along which multicast data of group 225.2.1.1 travels from source 10.11.5.24 to destination 192.168.2.2 and display brief mtrace information.

Predefined user roles

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

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

slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member device, this command clears multicast fast forwarding entries for the master device.

all: Specifies all multicast fast forwarding entries.

Examples

# Clear all multicast fast forwarding entries on the public network.

<Sysname> reset multicast fast-forwarding cache all

# Clear the multicast fast forwarding entry for multicast source and group (20.0.0.2, 225.0.0.2) on the public network.

<Sysname> reset multicast fast-forwarding cache 20.0.0.2 225.0.0.2
