Output Fields

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

Table 1: show multicast snooping route Output Fields

Field Name

Field Description

Level of Output

Nexthop Bulking

Displays whether next-hop bulk updating is ON or OFF (only for routing-instance type of virtual switch or vpls).

All levels


IPv4 address family (INET) or IPv6 address family (INET6).

All levels


Group address.

All levels


Prefix and length of the source as it is in the multicast forwarding table. For (*,G) entries, this field is set to "*".

All levels


Name of the routing instance to which this routing information applies. (Displayed when multicast is configured within a routing instance.)

All levels

Learning Domain

Name of the learning domain to which this routing information applies.

detail extensive


Rate at which packets are being forwarded for this source and group entry (in Kbps and pps), and number of packets that have been forwarded to this prefix.


EX4600, EX4650, and the QFX5000 line of switches don’t provide packet rates for multicast transit traffic at Layer 2, and any values displayed in this field for kBps and pps are not valid. Up until and including the following Junos OS Release versions, the same is true of the packet count (packets value in this field is also not a valid count): Junos OS Releases 18.4R2-S2, 19.1R2-S1, 19.2R1, 19.3R2, and 19.4R1. Starting after those Junos OS releases, EX4600, EX4650, and QFX5000 switches count packets forwarded to this prefix and display valid statistics for the packets value only.

detail extensive

Next-hop ID

Next-hop identifier of the prefix. The identifier is returned by the router's Packet Forwarding Engine and is also displayed in the output of the show multicast nexthops command.

detail extensive

Route state

Whether the group is Active or Inactive.


Forwarding state

Whether the prefix is Pruned or Forwarding.


Cache lifetime/timeout

Number of seconds until the prefix is removed from the multicast forwarding table. A value of never indicates a permanent forwarding entry.
