eigrp neighbors uptime

I had some unusual slow response time in my core network for a brief time.

The only thing I could find is this on my FW and my Router on a stick.

 

 

FW Addr: 10.49.1.2

bcoh1fw50# sh eigrp neighbors

what does the uptime mean?

 

The vendor primary router to the MPLS is 10.49.1.196

The vendor backup router to the MPLS is 10.49.1.197

The backup router on a stick is 10.49.1.189

Hi, UPTIME indicates how long

Hi,

 

UPTIME indicates how long since the last time each neighbor was discovered.

 

H: lists the neighbors in the order this router was learned
Address: the IP address of the neighbors
+ Interface: the interface of the local router on which this Hello packet was received
Hold (sec): the amount of time left before neighbor is considered in “down” status
Uptime: amount of time since the adjacency was established
SRTT (Smooth Round Trip Timer): the average time in milliseconds between the transmission of a packet to a neighbor and the receipt of an acknowledgement.
RTO (Retransmission Timeout): if a multicast has failed, then a unicast is sent to that particular router, the RTO is the time in milliseconds that the router waits for an acknowledgement of that unicast.
Queue count (Q Cnt): shows the number of queued EIGRP packets. It is usually 0.
Sequence Number (Seq Num): the sequence number of the last update EIGRP packet received. Each update message is given a sequence number, and the received ACK should have the same sequence number. The next update message to that neighbor will use Seq Num + 1.

VenperumThanks for the

Venperum

Thanks for the response

 

lists the neighbors in the order this router was learned
These are the primary devices that are used in the core network.

Does this mean that somehow the core vendor router lost connection to these other devices and then was discovered again?

Hello, John. Check loggs on

Hello, John.

 

Check loggs on the router to see the cause for EIGRP neighbor down (it might be SIA).

Elapsed time (in hours

Elapsed time (in hours:minutes: seconds) since the local router first heard from this neighbor.

5w5d =  mean 5 week and 5 day
