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. |
