Hello guys. I’m trying and failing so far to create a link between two sites but keeping original network addresses and topology. The main idea is to connect both sites but keep them independent (in case of link failure, local sites will work just fine). Here is what I’ve got
The VPN is working pretty good, and I want to add a second link because I need some failover option, also this setup will increase the access speed between remote sites. I would like to keep them working together using different route costs, but I’m here to hear suggestions…
I tried several options. I made wireless link using station-bridge mode trying to make things as simple as I can, but I keep killing RB750 routers when link is attached to same LAN (probably because of broadcast storm). When I put the wireless bridge using SXT Lite 5 equipment in a different master port I can ping the routers on each end from the router itself, but I can’t ping remote router or any remote client on any workstation.
Please, guide me to do this. I can post any configurations needed for analysis.
You need to connect the sxt into main routers and let them to decide where to route the packets. Having them in internal networks is bad idea. Actually you can keep physical connection but run vlans as direct links between the sxt and main router to achieve the goal. Set the bridge over and put ip addresses of unused interval to the both vlan ends in main routers. While they start to talk directly, the half is done. Second half is to add routing scheme according to your needs. Don’t forget to mangle incoming connections to send responses back by the right way…
Thank you for this suggestion. Let me check if I got this right…
I need to link SXT equipment directly to my RB750, not a problem… But do I need to make Ethernet linked port separate from Master LAN? Because I had problems when using SXT on same logical network, RB CPU load goes to 100% until it stops responding. I will do it without VLAN for now, because I want to make configurations as simple as I can, for testing purposes I can move another router to the SXT location, and I can also provide extra Ethernet cable for this link.
Can you please provide a Wiki page or something on how to set the needed Mangle configurations? I’m new to Mikrotik world, and I’m trying to set everything up, but I’m on trial and error right now.
Another doubt is: I’m making wire link between two RB750 to simulate my SXT equipment on Bridge mode. Is this a valid laboratory? I’m testing this outside my production network, SXT is already on top of the roof.
Hello everyone, I’m posting today just for documentation purposes. I found a great solution for my problem. I’m using OSPF to link those two networks.
First of all, SXT equipment need to be connected directly to the router in a different LAN (it is possible to use VLAN to achieve this goal if your infrastructure does not allow a direct link - my case). In other words the ethernet port you use to connect the Antenna must be “master-port=none”
I did SXT equipments to be on network 192.168.88.0/24, and also my Ether3. “/ip address add address=192.168.88.4/24 interface=ether3”
I made a single area OSPF configuration as mentioned in here: http://wiki.mikrotik.com/wiki/Manual:OSPF-examples
RB750_A Instance: name=“default” router-id=0.0.0.1 redistribute-connected=as-type-1
RB750_A Network: network=192.168.88.0/24 area=backbone
RB750_B Instance: name=“default” router-id=0.0.0.2 redistribute-connected=as-type-1
RB750_B Network: network=192.168.88.0/24 area=backbone
After this IP routes are created dynamically, and you can fine tune other configurations as Distance and alternative Default routes.
Hope this helps someone else with the same issue.
Cheers
