= Bug =
== Static Route ==
As of 3rd June 2015 there is a known bug with Raspbian that always obtains an IP address from DHCP even if a static IP address is configured.  This means that the rPi will obtain 2 individual IP address on the NIC.  The static been the primary and the DHCP IP been the additional.
 
To fix this problem if DHCP is not required
<pre>
<pre>
apt-get autoremove dhcpcd5
vi /lib/dhcpcd/dhcpcd-hooks/40-routes
</pre>
</pre>


You can also optionally remove
This will add a static route via interface eth0.11 which is on Vlan.11.  you could just specify eth0.
 
<pre>
<pre>
apt-get autoremove isc-dhcp-client isc-dhcp-common
ip route add 192.168.0.0/16 via 192.168.99.254 dev eth0.11 proto static
</pre>
</pre>

Debian 12

Set IP

Find the interface name. 

nmcli c show

Configure IP settings. 

nmcli con mod "Wired connection 1" ipv4.addresses 10.13.13.235/24 ipv4.method manual
nmcli con mod "Wired connection 1" ipv4.gateway 10.13.13.254
nmcli con mod "Wired connection 1" ipv4.dns "10.13.13.240"


For mutiple IP or DNS settings. 

nmcli con mod "Wired connection 1" ipv4.addresses 10.13.13.235/24, 192.168.1.235/24 ipv4.method manual
nmcli con mod "Wired connection 1" ipv4.dns "8.8.8.8, 8.8.4.4"

Reset interface

Reset or reboot. 

nmcli con down "Wired connection 1" && nmcli con up "Wired connection 1"

Show Settings

nmcli -p connection show "Wired connection 1"


Debian 11

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
