The Lazy Networker

Here i am going to explain how to change paths using delay in EIGRP, We already know that EIGRP uses Bandwidth and Delay for metric calculation but we cant change bandwidth of links in production network . The path with lesser delay will be the desired path.

In the above topology there are two paths to reach 192.168.23.0/24 network from R1  and right now R1 uses both links for load balancing because both having same metric.But i want to use only path to reach that destination and i going to do that with the help of delay.

I am going to decrease  the delay in R1->R3 by that metric will also decrease and R1 prefer that path to reach 192.168.23.0/24.

R1

interface Serial1/1
bandwidth 512
ip address 172.16.13.1 255.255.255.252
delay 1000
serial restart-delay 0
end

Now there is only one path to reach that network 🙂
