PhilipDAth: The existing Microwave link is connected via Cisco 4900m to 3850stack with backup 802.11 on different switches. That said, I was requested to design using only Meraki equipment as the Cisco devices are no longer under maintenance and will be retired - they want to move completely over to Meraki by attrition. During a microwave and Internet failure, the LTE link will only be used by EOC mail and web services - via traffic shaping. We may completely remove the police VLAN from transportation - this is still in discussion. I brought this up about 6 months ago to the government cisco rep. I had trouble getting him to use only Meraki equipment 😉

Yes. Normally, the 10 Mbs internet connection in Transportation is not used. Only for failover.

The Internet VLAN (100) is connected to 2 Cisco routers using BGP to the two Internet links. It has as a 24 bit subnet and can be routed from either building's Internet router (currently a Cisco 2800 router and an ASA). The police VLAN (101) 24 bit subnet , and City networks (102-130) 20 bit subnets, are current working across a trunk port like: Cisco 4900m -- Microwave 1 Gbs -- Cisco 3850 (primary) (Spanning Tree enforced) Cisco 4900m -- 802.11 30 Mbs -- Cisco 3850 (backup) (Spanning Tree enforced) This link has failed (after 11 years 😉 and I have the opportunity to spec out a new solution. There are rules to where the City network and Police network can access. I might remove the police VLAN from transportation completely (some new networking rules are coming down the pipeline). I am hoping for something like: Meraki MX100 -- Microwave 1 Gbs -- Meraki MX100 (load balanced) Meraki MX100 -- Microwave 1 Gbs -- Meraki MX100 (load balanced) And have a 2 Gbs links between buildings with failover to 1 Gbs

The microwave radios connect from building to building. Internal only. Not an Internet link. I am treating this as if they were fiber links between buildings.

Both sides of the microwave link have their own Internet links - 1 Gbs and 10 Mbs. For most users, the Internet access is via the 1 Gbs link, if that is down, then all users will go out the 10 Mbs link. If the 10 Mbs link is down, I expect to have a LTE Lin up with traffic shaping rules that allow only specific high priority traffic.

Hi Community! I need to implement a redundant/load balancing system between to buildings about 5 miles apart. We are connected via 2 microwave links (on different towers, two 1Gb feeds from each tower), VPN via Internet (1Gb and 10 Mb), and maybe a LTE device to get some email out if all the above goes pear shaped. I was planning on initial 2 MX100's then add two more as warm spares. I expect each mx100 would look like: MX -- WAN1 -- Internet (Access VLAN 100, Auto VPN) MX -- usb -- Modem LTE Internet failover MX -- GbE1 -- Microwave 1, Radio 1 (Trunk) MX -- GbE2 -- Microwave 1, Radio 2 (Trunk) MX -- GbE3 -- Microwave 2, Radio 1 (Trunk) MX -- GbE4 -- Microwave 2, Radio 2 (Trunk) MX -- GbE5 -- Core network (Bonded) MX -- GbE6 -- Core network (Bonded) MX -- GbE7 -- Core network (Bonded) MX -- GbE8 -- Core network (Bonded) Will this work? Better ideas? Thank you. Initial drawing below.
