Description

Display information about multicast reverse-path-forwarding (RPF) calculations.

Options

none

Display RPF calculation information for all supported address families.

inet | inet6

(Optional) Display the RPF calculation information for IPv4 or IPv6 family addresses, respectively.

instance instance-name

(Optional) Display information about multicast RPF calculations for a specific multicast instance.

logical-system (all | logical-system-name)

(Optional) Perform this operation on all logical systems or on a particular logical system.

prefix

(Optional) Display the RPF calculation information for the specified prefix.

summary

(Optional) Display a summary of all multicast RPF information.

Output Fields

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

Table 1: show multicast rpf Output Fields

Field Name

Field Description

Instance

Name of the routing instance. (Displayed when multicast is configured within a routing instance.)

Source prefix

Prefix and length of the source as it exists in the multicast forwarding table.

Protocol

How the route was learned.

Interface

Upstream RPF interface.

Note:

The displayed interface information does not apply to bidirectional PIM RP addresses. This is because the show multicast rpf command does not take into account equal-cost paths or the designated forwarder. For accurate upstream RPF interface information, always use the show pim join extensive command when bidirectional PIM is configured.

Neighbor

Upstream RPF neighbor.

Note:

The displayed neighbor information does not apply to bidirectional PIM. This is because the show multicast rpf command does not take into account equal-cost paths or the designated forwarder. For accurate upstream RPF neighbor information, always use the show pim join extensive command when bidirectional PIM is configured.
