Follow up, I found out that is correct with VPLS. However, I had two bridges on a router each containing a separate VPLS endpoint/interface in them that had the same MAC address. The MikroTik bridge assumes the MAC address of one of the member ports, not sure how it figures out which port MAC address to use.
In one case it had select the VPLS tunnel MAC in both bridges for the two spate VPLS endpoints, that happened to have the same MAC. So I ended up with two bridges on the router with the same MAC address. This caused a bridge loop, or at least a notification of a bridge loop my having the same MAC address show up in cycle. Very interesting. -----Original Message----- From: Af [mailto:[email protected]] On Behalf Of Sterling Jacobson Sent: Saturday, July 1, 2017 1:46 AM To: '[email protected]' <[email protected]> Subject: [AFMUG] Mikrotik VPLS MAC Address I noticed on Mikrotik you can assign/change a MAC address to a VPLS interface. Is that MAC address supposed to be always unique? Several of mine on any given device are using the same MAC address.
