Entry | Description |
|---|---|
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. |
