Note: For show ip pim (vrf NAME|) interface detail command:
• Output shall contain 'Bidirectional Forwarding Detection is enabled' in case PIMv4 BFD is enabled on an interface either by global command or at interface level.
• Output shall contain 'Bidirectional Forwarding Detection is disabled' in case PIMv4 BFD is explicitly disabled on an interface.
 
Table 1-20: Show ip pim interface output
Entry
Description
Address
IP address of the interface
Interface
Interface name (eth1, xe3, ge4/1, etc.).
VIFindex
The index number of the Virtual Host Interface (vif).
Ver/Mode
PIM version (either v1, v2, or v3) / PIM Mode – Either S (sparse mode) or D (dense mode).
Nbr Count
Neighbor Count.
DR Prior
Designated Router Priority.
DR
Address of the Designated Router.
Hello Period
Routing devices send hello messages at a fixed interval on all PIM-enabled interfaces. By using hello messages, routing devices advertise their existence as PIM routing devices on the subnet.
Next Hello
When the interval counts down to 0, the routing device sends another hello message, and the timer is reset. A routing device that receives no response from a neighbor in 3.5 times the interval value drops the neighbor.
Propagation Delay
Vif Hello LAN Delay – propagation delay in milliseconds.
ECMP Redirect, bundle
An ECMP bundle is a set of PIM-enabled interfaces on a router, where all interfaces belonging to the same bundle share the same routing metric. The next hops for the ECMP are all one hop away. There can be one or more ECMP bundles on any router, while one individual interface can only belong to a single bundle. ECMP bundles are created on a router via configuration.
Neighbors
A list of the addresses of PIM multicast neighbors.
