MSDP Source-Active Cache

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.

(*, *, RP) Entries:

Source, Group, Rendezvous Point Include entries.

(*, G) Entries:

PIM Include entries

(S, G) Entries:

PIM Include entries (Source, Group)

(S, G, rpt) Entries:

The RPT is the path between the RP and receivers (hosts) in a multicast group. The RPT is built by means of a PIM join message from a receiver's DR.

RP:

Rendezvous Point

RPF nbr:

Reverse Path Forwarding neighbor.

RPF idx:

Reverse Path Forwarding index.

Upstream State:

As stated.

Neighbor

Neighbor IP address

Interface

Name of the interface (eth1, xe3, xe5/1 etc.).

Uptime/Expires

Neighbor’s uptime / time until uptime expires and starts sending hello messages.

Ver

PIM version (version1 =v1, version2 - v2, version3 = v3).

DR Priority/mode

Priority and Mode of neighbor as Designated Router.

Nbr

NEighbor IP address and interface name (eth1, xe3, xe5/1 etc.).

Expires in

Time before the Hello timer expires and must retransmit.

uptime

Neighbor uptime.

Holdtime:

Before an interface goes down or changes primary IP address, a Hello message with a zero HoldTime should be sent immediately (with the old IP address if the IP address changed). This will cause PIM neighbors to remove this neighbor (or its old IP address) immediately. After an interface has changed its IP address, it MUST send a Hello message with its new IP address. If an interface changes one of its secondary IP addresses, a Hello message with an updated Address_List option and a non-zero HoldTime should be sent immediately. This will cause PIM neighbors to update this neighbor's list of secondary addresses immediately.

T-bit:

RPT-bit is a 1-bit value. The RPT-bit is set to 1 for Assert(*,G) messages and 0 for Assert(S,G) messages.

Lan delay:

In addition to the information recorded for the DR Election, the following per neighbor information is obtained from the LAN Prune Delay Hello option:

In addition to the information recorded for the DR Election, the following per neighbor information is obtained from the LAN Prune Delay Hello option:

 

neighbor.lan_prune_delay_present

A flag indicating if the LAN Prune Delay option was present in

the Hello message.

 

neighbor.tracking_support

A flag storing the value of the T bit in the LAN Prune Delay

option if it is present in the Hello message. This indicates

the neighbor's capability to disable Join message suppression.

 

neighbor.propagation_delay

The Propagation Delay field of the LAN Prune Delay option (if

present) in the Hello message.

 

neighbor.override_interval

The Override_Interval field of the LAN Prune Delay option (if

present) in the Hello message.

 

The additional state described above is deleted along with the DR neighbor state when the neighbor timeout expires.

 

Override interval:

Hello Override Interval

DR priority:

The DR_Priority Option allows a network administrator to give preference to a particular router in the DR election process by giving it a numerically larger DR Priority.The DR_Priority Option SHOULD be included in every Hello message, even if no DR Priority is explicitly configured on that interface. This is necessary because priority-based DR election is only enabled when all neighbors on an interface advertise that they are capable of using the DR_Priority Option. The default priority is 1.

Gen ID:

Generation Identifier, used to detect reboots.

Interface ID:

As stated.

Router-ID:

As stated.

Local-ID:

As stated.

ECMP REDIRECT

Whether ECMP Redirect is enabled or disabled.

BSR address
