Advanced Networking
How to configure advanced networking options on Talos Linux.
Static Addressing
Static addressing is comprised of specifying addresses, routes ( remember to add your default gateway ), and interface.
Most likely you’ll also want to define the nameservers so you have properly functioning DNS.
yaml
machine:
network:
hostname: talos
nameservers:
- 10.0.0.1
interfaces:
- interface: eth0
addresses:
- 10.0.0.201/8
mtu: 8765
routes:
- network: 0.0.0.0/0
gateway: 10.0.0.1
- interface: eth1
ignore: true
time:
servers:
- time.cloudflare.comAdditional Addresses for an Interface
In some environments you may need to set additional addresses on an interface. In the following example, we set two additional addresses on the loopback interface.
yaml
machine:
network:
interfaces:
- interface: lo
addresses:
- 192.168.0.21/24
- 10.2.2.2/24Bonding
The following example shows how to create a bonded interface.
yaml
machine:
network:
interfaces:
- interface: bond0
dhcp: true
bond:
mode: 802.3ad
lacpRate: fast
xmitHashPolicy: layer3+4
miimon: 100
updelay: 200
downdelay: 200
interfaces:
- eth0
- eth1Setting Up a Bridge
The following example shows how to set up a bridge between two interfaces with an assigned static address.
yaml
machine:
network:
interfaces:
- interface: br0
addresses:
- 192.168.0.42/24
bridge:
stp:
enabled: true
interfaces:
- eth0
- eth1VLANs
To setup vlans on a specific device use an array of VLANs to add. The master device may be configured without addressing by setting dhcp to false.
yaml
machine:
network:
interfaces:
- interface: eth0
dhcp: false
vlans:
- vlanId: 100
addresses:
- "192.168.2.10/28"
routes:
- network: 0.0.0.0/0
gateway: 192.168.2.1
