eigrp feasible successor

Unanswered Question
Jul 7th, 2008


I just want to know if this how eigrp show a feasible successor

for exemple:

P, 1 successors, FD is 29468416

via (29468416/21845248),Serial1/1

via (57912832/21845248), Serial1/0

is the route via is a FS?

The route via is the first feasible sucessor, the route via is the other.

An example from one of my routers is:-

P x.x.x.x/8, 1 successors, FD is 129767680

via x.x.x.x (129767680/129765120), FastEthernet0/0.2

via x.x.x.x(385250304/128025344), Tunnel3

via x.x.x.x(641250560/128025600), Tunnel4

show ip route says: ( in my exemple)

that the route to is via with metric 29468416


there is a successor

and a FS :via (57912832/21845248), Serial1/0

its all right

do you know how to change the K values?

You change the K values in the EIGRP process. the default K values used are bandwidth and Delay. The command is:-

metric weights tos k1 k2 k3 k4 k5

The command defaults to a setting of 0 1 0 1 0 0, meaning that only bandwidth and delay are used to calculate the metric
