Any old number you want. They're completely arbitrary. But, any port in a bridge with the same horizon, traffic won't go from one to the other.
So yeah, if you wanted two separate partitions, some would have horizon 1, some would have horizon 2. If you have, say, a VPLS tunnel as part of the bridge, you put it on a different horizon, so traffic from it can go to all the other ports, and traffic from any port can go to it, but traffic can't go from port to port. /interface bridge add name=mybridge /interface bridge port add bridge=mybridge interface=ether1 horizon=1 /interface bridge port add bridge=mybridge interface=ether2 horizon=1 /interface bridge port add bridge=mybridge interface=ether3 horizon=1 /interface bridge port add bridge=mybridge interface=ether4 horizon=1 /interface bridge port add bridge=mybridge interface=ether5 horizon=1 /interface bridge port add bridge=mybridge interface=my-vpls-tunnel horizon=2 -----Original Message----- From: mikrotik-boun...@mail.butchevans.com [mailto:mikrotik-boun...@mail.butchevans.com] On Behalf Of Martín Ruiz Sent: Thursday, February 12, 2015 5:25 PM To: Mikrotik discussions Subject: Re: [Mikrotik] Split-horizon on CRS125 And what if you want to make 2 groups?
