Description

Display the entries in the IP multicast next-hop table.

Options

none	Display standard information about all entries in the multicast next-hop table for all supported address families.
brief \| detail \| terse	(Optional) Display the specified level of output. Use `terse` to display the total number of outgoing interfaces (as opposed to listing them) When you include the detail option on M Series and T Series routers and EX Series switches, the downstream interface name includes the next-hop ID number in parentheses, in the form fe-0/1/2.0-(1048574), where 1048574 is the next-hop ID number. Starting in Junos OS release 16.1, the `show multicast next-hops` statement shows the hierarchical next hops contained in the top-level next hop.
`identifier-number`	(Optional) Show a particular next hop by ID number. The range of values is 1 through 65,535.
inet \| inet6	(Optional) Display entries for IPv4 or IPv6 family addresses, respectively.
logical-system (all \| `logical-system-name`)	(Optional) Perform this operation on all logical systems or on a particular logical system.
satellite	Show satellite multicast unicast next-hops
session	Show all MCNH session IDs

Output Fields

Table 1 describes the output fields for the show multicast next-hops command. Output fields are listed in the approximate order in which they appear.

Table 1: show multicast next-hops Output Fields
Field Name	Field Description
Family	Protocol family (such as INET).
ID	Next-hop identifier of the prefix. The identifier is returned by the routing device's Packet Forwarding Engine.
Refcount	Number of cache entries that are using this next hop.
KRefcount	Kernel reference count for the next hop.
Downstream interface	Interface names associated with each multicast next-hop ID.
Incoming interface list	List of interfaces that accept incoming traffic. Only shown for routes that do not use strict RPF-based forwarding, for example for bidirectional PIM.
