Hi Mike,
Thanks for your support! The command I am using is as below:
esxcli network ip route ipv4 add -g 10.20.27.253 -n 10.28.184.0/22 where 10.28.184.0/22 is the network to reach via vmk3 and 10.20.27.253 is the main default gateway which is available in host's configuration , dns & routing section to be specific. That means the VM's deployed on the vmk3 port group should get the dhcp ipv4 addresses from 10.28.184.0/22 which is not happening instead some 169.x.x.x addresses are assigned.
thanks
sai
