q about EIGRP

[doshi.devang]

on page num 435 and 439 through R1 router when performed sh ip router .
why difference in output??

on 435 for each remote n/w 2 route has shown

while on 439 only one route

why is it like that?? how can i switch my o/p like this??

hii
no no its not abt de output...
on pg 435 sh ip route is showing all the route and dere was a tie b/w two route having same cost so both are shown in output..but after that on r1 we have change the bandwidth and delay....so cost of one route changes wid respect to another..so only the best route is shown in routing table....
Perviously they are --->load sharing
on pg439 --->no load sharing becoz of unequal cost...

if you want to see both the route use sh ip eigrp topology
you will see both route and if you want that unequal path should also share load
den dere is comand
variance (multiplier)

thanx anurag

i completely understand what u replied... but how do i use variance command? do i use on all the routers like corp, r1, r2 and r3? or only r1?

devang:confused:

Variance is used on a per-AS basis (if a router is running more than one instance of EIGRP, oyu can specify different variance for each instance). You have to remember though that only feasible successors can be included in the routing table with this command. This means that the AD of the route must be lower than the FD of the successor route.

variance multipler...comand used for load balancing
how to use :
fd(suceescor) multipy by X(multiplier) == fd(fesable succesor)

calculate x in above dats ur variance...

do in example suppose wen u enter command sh ip eigrp topology
successor fd = 5 (hypothetical)
x (we dont knw)
fesable successor Fd = 10(hypothetical)

5 multiply by x = 10
so multiplier is 2
so use comand
variance 2
and nw both the route wil be sown in routing table....
