VETH
CLI reference:/interface/veth
VETH (Virtual Ethernet) is a virtual network interface that provides network connectivity for containers. It functions as a virtual Ethernet port that connects RouterOS to a container, enabling 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 a DHCP client, and support SLAAC. Additionally, VETH interfaces can participate in bridge 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.
