EIGRP Narbik Advance Tech.

 

Ok so this is my interpretation of EIGRP ADVANCE TECH LAB, Infact I have re-written the tasks description down in my own words. I found this approach to be the best, as during the lab we have apple of paper and coloured pencils/pens to work with.

 

What follows below are the tasks list and command references for the same.

 

Task 1) Command reference:

conf t

router eigrp <asn>

no auto-summary

network <network no> <wld mask>

end

 

Task 2)Command reference:

interface serial 3/0

(config-if)#ip hello-interval eigrp 10 20

(config-if)#ip hold-time eigrp 10 80

 

T3)Command reference:

router eigrp 100

(config-router)#metric weights 0 1 0 0 0 0

 

 

T4)Command reference:

router eigrp 100

(config-router)#metric weights 0 0 0 1 0 0

 

T5)Command reference:

We need to make use of LEAK-MAP,LEAK-MAPS are available along with the summary command. The way leak maps work are highlighted below,

LEAK_MAP	ROUTE_MAP	ACL	RESULT
Yes	No	No	Only Sum
Yes	Yes	No	Sum + All
Yes	Yes	Yes	Sum + ACL Match

 

R1(config-subif)#ip summary-address eigrp 300 1.1.0.0 255.255.252.0 leak-map R1->R2
