show pim interfaces

Syntax

show pim interfaces
<inet | inet6>
<instance instance-name>
<logical-system (all | logical-system-name)>

Release Information

Command introduced before JUNOS Release 7.4.

Description

Display information about the interfaces on which Protocol Independent Multicast (PIM) is configured.

Options

none — Display interface information for all family addresses for all routing instances on all logical systems.

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

instance instance-name — (Optional) Display information about interfaces for a specific PIM-enabled routing instance.

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

Required Privilege Level

Output Fields

Field Name

Field Description

Instance

Name of the routing instance.

Name

Interface name.

State

State of the interface. The state also is displayed in the show interfaces command.

Mode

PIM mode running on the interface:

  • Sparse—In sparse mode, routers must join and leave multicast groups explicitly. Upstream routers do not forward multicast traffic to this router unless this router has sent an explicit request (using a join message) to receive multicast traffic.
  • Dense—Unlike sparse mode, where data is forwarded only to routers sending an explicit request, dense mode implements a flood-and-prune mechanism, similar to DVMRP (the first multicast protocol used to support the Multicast Backbone).
  • Sparse-Dense—Sparse-dense mode allows the interface to operate on a per-group basis in either sparse or dense mode. A group specified as dense is not mapped to a rendezvous point (RP). Instead, data packets destined for that group are forwarded using PIM-Dense Mode (PIM-DM) rules. A group specified as sparse is mapped to an RP, and data packets are forwarded using PIM-Sparse Mode (PIM-SM) rules.

IP

Version number of the address family on the interface: 4 (IPv4) or 6 (IPv6).

V

PIM version running on the interface: 1 or 2.

State

State of PIM on the interface:

  • DR—Designated router.
  • NotDR—Not the designated router.
  • P2P—Point to point.

Count

Number of neighbors that have been seen on the interface.

DR address

Address of the designated router.
