Hi Folks,
Please find the steps to increase the metric. In my setup the default traffic from r2 to r5 is via r3. I will increase the metric between r2-r3 to divert the traffic from r2 via r4 as below.
r2 lo0.102 192.168.1.102
r3 lo0.103 192.168.1.103
r4 lo0.104 192.168.1.104
r5 lo0.105 192.168.1.105
