Set up VLAN on eth0, worked great.
sudo nano /etc/network/interfaces.d/vlans
auto eth0.16
iface eth0.16 inet manual
vlan-raw-device eth0
sudo nano /etc/dhcpcd.conf
interface eth0.16
static ip_address=10.20.36.2/23
static routers=10.20.37.1
static domain_name_servers=1.1.1.1
Made this change to dhcpcd.conf:
interface eth0.16
static ip_address=10.20.16.12/23 # changed from 10.20.26.2
static routers=10.20.17.1 # changed from 10.20.37.1
static domain_name_servers=1.1.1.1
Rebooted
hostname -I 192.168.x.x 10.20.36.2 // eth0.16 did not change
What do I have to do to get the I.P. address changed?
