Bridging

Interface Bridging

MikroTik RouerOS supports MAC level bridging of Ethernet packets. Ethernet, Ethernet over IP (EoIP), Prism, Atheros and RadioLAN interfaces are supported. The Bridge Interfaces can also be Firewalled.

Spanning Tree Protocol (STP)
Multiple bridge interfaces
Bridge associations on a per interface basis
Protocol can be selected to be forwarded or discarded
MAC address table can be monitored in real time
IP address assignment for router access
Bridge interfaces can be firewalled

Transparent Bridging of Remote LANs

Remote LANs can be transparently bridged over secure VPN connections by means of Ethernet over IP tunnels and Ethernet bridge. One MikroTik Router is required per one remote LAN. The Routers should be able to communicate with each other over public network. Secure VPN tunnels are established between them. EoIP tunnels are run over these VPN connections with bridging between EoIP and LAN interfaces.
