Manual:BCP bridging (PPP tunnel bridging)
Applies to RouterOS: v3, v4
Summary
RouterOS supports BCP (Bridge Control Protocol) for PPP, PPTP, L2TP and PPPoE interfaces. BCP allows to
bridge Ethernet packets through the PPP link. Established BCP is independent part of the PPP tunnel, it is not related
to any IP address of PPP interface, bridging and routing can happen at the same time independently. BCP can be
used instead of EoIP + used VPN Tunnel or WDS link over the wireless network.
Requirements
BCP (Bridge Control Protocol) should be enabled on both sides (PPP server and PPP client) to make it work.
MikroTik RouterOS can be used with other PPP device, that supports BCP accordingly to the standards, but BCP
enabled is necessary.
Configuration Example
We need to interconnect two remote offices and make them in one Ethernet network. We have requirement to use
encryption to protect data exchange between two offices. Let's see, how it is possible with PPTP tunnel and BCP
protocol usage
