interfaces

make sure the interfaces file has not been modified.

vi /etc/network/interfaces

The default settings are:

# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

dhcpcd.conf

vi /etc/dhcpcd.conf

Append the following. The entry of static will stop the server looking for an IP address from DHCP.

interface eth0
static ip_address=192.168.13.200/24
static routers=192.168.13.1
static domain_name_servers=8.8.8.8 8.8.4.4
static domain_search=mydomain.com ap.mydomain.com

Alias

Temporary

To create a temporary alias rather than a permanent one you can issue the following command from the CLI.

ifconfig eth0:0 192.168.22.1/24

IPv6

The domain names servers can have a mix of IPv4 and IPv6 servers.

vi /etc/dhcpcd.conf
static ip6_address=2321:3fa4:4f7a:d100::1234/64
static domain_name_servers=2001:4860:4860::8888 2001:4860:4860::8844

VLAN

Load 8021q Module

vi /etc/modules

Add the line

8021q

Create Interface

Define a VLAN for a specific interface.

vi /etc/network/interfaces
# VLAN 101 Interface
auto eth0.101
iface eth0.101 inet manual
    vlan-raw-device eth0

Assign IP Address

Set a static IP for new interface

vi /etc/dhcpcd.conf
# Static IP configuration for VLan.101
interface eth0.101
static ip_address=192.168.1.101/24

Static Route

vi /lib/dhcpcd/dhcpcd-hooks/40-routes

This will add a static route via interface eth0.11 which is on Vlan.11. you could just specify eth0.

ip route add 192.168.0.0/16 via 192.168.99.254 dev eth0.11 proto static
