Forwarding multiple VLAN traffic through SXT 5 PTP Bridge

RouterOS General
1

hi,

i have setup an SXT 5 PTP wireless Bridge between two locations in case of a cable breakdown.

the entire network has around 10 VLAN’s

when the bridge works it just forwards the traffic of the VLAN it is connected to physically.

there are following VLAN’s

ID: VLAN200
IP: 192.9.200 .xxx
Subnet : 255.255.255.0
Gateway: 192.9.200.254

ID: VLAN207
IP: 192.168.207 .xxx
Subnet : 255.255.255.0
Gateway: 192.168.207.254

ID: VLAN209
IP: 192.168.209 .xxx
Subnet : 255.255.255.0
Gateway: 192.168.209.254

i am looking at PTP wireless using the bridge as a failover to physical ethernet cable between two buildings.

can you please tell me how can i forward the mentioned VLAN’s and any further ones if incorporated using the PTP Bridge seamlessly irrespective of which network ports the SXT 5 PTP wireless bridge is plugged into.

hello friends… can someone help me with this please… it’s fairly urgent.

could someone please shed some light on this issue…

You need to setup a VLAN trunk on the port the SXT is attached to.

The SXT will then pass the VLANs assigned to this port.

hi,

thank you for the reply.

the SXT has one ETHERNET and one WLAN port and both are in “Bridged” mode for communicating called the “Bridge1” interface.

so now the “Bridge1” interface is carrying the traffic for both Ethernet and WLAN as a single port.

the same is on the other side of the unit as it is PTP scenario.

the link you gave me is showing how to do it on a router with multiple ports.

how can i get that done for this Bridge?

Your network at each site will be something like -

Configure a VLAN trunk port on the switch ports connecting to your SXT wireless links. Like port 2 in the diagram. In bridge mode they will pass the VLAN tagged packets.

hi,

i really appreciate your help but i am still confused how to setup a switch port with VLAN connection to BRIDGE1 (WLAN+ETH)…

the diagram you showed is showing multiple ethernet ports which is confusing me more.

can you send me a “code” for that if possible?

Add vlan to the bridge and you will have vlans on all interfaces of the bridge.

9

so in my case do i just need to create 3 VLAN’s from the Interface option and give the respective ID 200, 207 and 209 and select their interface as BRIDGE1 … am i right?

and do i have to do it on both sides of the SXT?

10

In mikrotik all vlans are passed by default under transparent bridge configuration.you dont need to add any extra rule for it.

11

And for the failover setup configure RSTP ring on manageable switches at both end.

hi,

can you please tell me what do you exactly mean by transparent bridge?

13

By transparent i mean that you have not configured any bridge firewall and have simply created a bridge and added ports to it.

do i need to plug the SXT in the trunk port of CISCO Switch to pass the VLAN traffic over the SXT 5 PTP Bridge?
