Options

none

Display detailed information.

brief | detail | extensive

(Optional) Display the specified level of output.

instance instance-name

(Optional) Display PIM snooping join information for the specified routing instance.

Output Fields

Table 1 lists the output fields for the show pim snooping join command. Output fields are listed in the approximate order in which they appear.

Table 1: show pim snooping join Output Fields

Field Name

Field Description

Level of Output

Instance

Routing instance for PIM snooping.

All levels

Learning-Domain

Learning domain for PIM snooping.

All levels

Group

Multicast group address.

All levels

Source

Multicast source address:

  • * (wildcard value)

  • <ipv4-address>

  • <ipv6-address>

All levels

Flags

PIM flags:

  • bidirectional—Bidirectional mode entry.

  • 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.

All levels

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 join messages nor prune messages toward the RP, because this router is the rendezvous point.

  • Local Source—Sending neither join messages nor prune messages toward the source, because the source is locally attached to this routing device.

  • Prune to RP—Sending a prune to the rendezvous point.

  • Prune to Source—Sending a prune to the source.

Note:

RP group range entries have None in the Upstream state field because RP group ranges do not trigger actual PIM join messages between routers.

All levels

Upstream neighbor

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

For bidirectional PIM, Direct means that the interface is directly connected to a subnet that contains a phantom RP address.

All levels

Upstream port

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).

For bidirectional PIM, RP Link means that the interface is directly connected to a subnet that contains a phantom RP address.

All levels

Downstream port

Information about downstream interfaces.

extensive

Downstream neighbors

Address of the downstream neighbor.

extensive

Timeout

Time remaining until the downstream join state is updated (in seconds).
