IPv6 EIGRP debug output
I have been analyzing the debug output of EIGRP IPv6 and am not sure which times to take. The time when the DLS1 interface was shut or enabled in written before the debug output. The first output was somehow simple because I have taken the time when the route has been added to the Routing Information base. On the 2nd output was the tricky one , what I have considered is when FEC0::6:0/112 has been deleted. The logic being that , this when this route is being removed from the table because it can not be accessed due to a shut down interface. I stand to be corrected. The duration taken for each route to be removed or added is just below each output.
Interface fa0/1 was enabled on DLS1 @ 11:59:55.422

You need to use up

and may be

It is difficult to find out without the toplogy. How many and which debug where running at the time?
Well, I will send the topology to you on the e-mail since I failed to put the topology diagram last time. Three debug were running on R1 ,R2 R3 & R4.. I had brought all results as per my calculation yesterday as per the request i made by mail but i did not get a response from you. I can put up two outputs from each router.
Thanks
