I am able to config fixed ip address with hardware ethernet options, but i am trying to assign fixed ip based on client id(option 61) from DISCOVER message. I tried with below configs , but it doesn't help.
host virtual_1
{
dhcp-client-identifier = 00:00:00:00:01
option routers 10.1.1.49;
option host-name "virtual1";
#hardware ethernet 00:01:02:03:04:05;
fixed-address 10.1.1.179;
option ntp-servers 10.1.1.49;
}
