display multicast rpf-info

Function

The display multicast rpf-info command displays the Reverse Path Forwarding (RPF) routes of a specified IPv4 multicast source or source/group.

Format

display multicast [ vpn-instance vpn-instance-name | all-instance ] rpf-info source-address [ group-address ] [ rpt | spt ]

Parameters

Parameter	Description	Value
vpn-instance vpn-instance-name	Specifies a VPN instance. vpn-instance-name specifies the name of the VPN instance.	The value must be an existing VPN instance name.
all-instance	Indicates all the instances.	-
source-address	Specifies the address of a multicast source, used to display the information of RPF routing corresponding to the source.	The address is in dotted decimal notation.
group-address	Specifies the multicast group address, used to display the information of RPF routing corresponding to the source/group.	The address is in dotted decimal notation and ranges from 224.0.1.0 to 239.255.255.255.
rpt	Displays the RPF routing information corresponding to a specified source or source/group on the shared RP-tree.	-
spt	Displays the RPF routing information corresponding to a specified source or source/group on the shortest path tree.	-

Usage Guidelines

The RPF route with the source-address as the destination address is an optimal route selected from unicast routes, multicast static routes, MBGP routes, and MIGP routes. You can use the display multicast rpf-info command to check the RPF route to the specified source or source-group.

Example

# Display all RPF routes to the source address 192.168.0.1.

<HUAWEI> display multicast rpf-info 192.168.0.1
 VPN-Instance: public net
 RPF information about source: 192.168.0.1
     RPF interface: Vlanif100, RPF neighbor: 10.1.5.2
     Referenced route/mask: 192.168.0.0/24
     Referenced route type: unicast
     Route selection rule: preference-preferred
     Load splitting rule: disable
