Overview

VETH (Virtual Ethernet) is a special type of virtual network interface primarily used to provide network connectivity for containers.
It acts as a virtual Ethernet port that connects RouterOS to a container, allowing the container to communicate with other interfaces and networks.

VETH interfaces behave like standard Ethernet interfaces — they can be assigned static IPv4 and IPv6 addresses, obtain addresses via DHCP client. VETH interfaces also support SLAAC.
They can also participate in bridges or routing configurations, just like physical interfaces.

Basic Configuration Example

There are multiple ways to configure VETH. Below are simple examples. 

# VETH with DHCP-client
/interface/veth add dhcp=yes

# VETH with static address
/interface/veth add address=10.1.1.10/24 gateway=10.1.1.1

After configuring the interface, you can assign it to a container.
The container should obtain either the IP assigned by the DHCP server or the static address.
