<brief | detail | extensive>
<inet | inet6>
<instance instance-name>

<range>

Release Information

Command introduced before JUNOS Release 7.4.

Description

Display information about Protocol Independent Multicast (PIM) groups.

Options

none — Display the standard information about PIM groups for all supported family addresses for all routing instances on all logical systems.

brief | detail | extensive — (Optional) Display the specified level of output.

inet | inet6 — (Optional) Display PIM group information for IPv4 or IPv6 family addresses, respectively.

instance instance-name — (Optional) Display information about groups for the specified PIM-enabled routing instance only.

logical-system (all | logical-system-name) — (Optional) Perform this operation on all logical systems or on a particular logical system.

range — (Optional) Address range of the group, specified as prefix/prefix-length.

Output Fields

Table 54: show pim join Output Fields

Field Name

Field Description

Instance

Name of the routing instance.

address-family

Name of the address family: inet (IPv4) or inet6 (IPv6).

Group

Group address.

Source

Multicast source:

  • * (wildcard value)
  • ipv4-address
  • ipv6-address

RP

Rendezvous point for the PIM group.

Flags

PIM flags:

  • dense—Dense mode entry.
  • rptree—Entry is on the rendezvous point tree.
  • sparse—Sparse mode entry.
  • spt—Entry is on the shortest-path tree for the source.
  • wildcard—Entry is on the shared tree.

Upstream interface

RPF interface toward the source address for the source-specific state (S, G) or toward the rendezvous point (RP) address for the non-source-specific state (*, G).

Upstream neighbor

Information about the upstream neighbor: Direct, Local, Unknown, or a specific IP address.

Upstream state

Information about the upstream interface:

  • Join to RP—Sending a join to the rendezvous point.
  • Join to Source—Sending a join to the source.
  • Local RP—Sending neither joins nor prunes toward the RP, because this router is the rendezvous point.
  • Local Source—Sending neither joins nor prunes toward the source, because the source is locally attached to this router.
  • Prune to RP—Sending a prune to the rendezvous point.
  • Prune to Source—Sending a prune to the source.

Downstream neighbors

Information about downstream interfaces:

  • Interface—Interface name for the downstream neighbor.

    Note: A pseudo PIM-SM interface appears for all IGMP-only interfaces.

  • Interface address—Address of the downstream neighbor.
  • State—Information about the downstream neighbor: join or prune.
  • Flags—PIM join flags: R (RPtree),S (Sparse), W (Wildcard), or zero.

Assert Timeout

Length of time between assert cycles on downstream interface. Not displayed if assert timer is null.

Timeout

Time remaining until the downstream join state is updated (in seconds). If the downstream join state is not updated before this keepalive timer reaches zero, the entry is deleted. If there is a directly connected host, Timeout is Infinity.
