Multiple ER605 , 4ISPs, Multiple Buildings connected over wireless bridges
I currently manage the network of a small non profit camp that sits on the edge of a lake. The lake is an old rock quarry. The camp has 20 plus buildings. I have the important buildings inconnected with wireless bridges, wireless because ground is not suitable to bury and topography is not suitable for an overhead line. We currently have 2 wireless isp connections which we load balance with an ER605. The camp has an opptroutnity to provide a location for some local schools to do test prep which needs more bandwidth in more locations than the current connections will adequatly supply. So the plan is to move one of the isps (Starlink) to the main office building. Add a second connection to the existing building. Then add a 3rd connection to a camp mangers home which is currently at end of daisy chained wireless bridges. The building with the 2 isps is the central hub as it currently is. What I think I need to do is set up 4 vlans.
- Vlan5 would be internet access for all locations.
- Vlan 1 would be camp manger which would have a dedicated isp connection and a failover to vlan5.
- Vlan2 would be the office location which would have the starlink isp and vlan5 and vlan1. The starlink conneciton would be put in standby mode and only active when the main ISP failed (it currently takes about 10 minutes to activate it). Most often the load from this end of the camp will be either the office or managers location not both so it makes sense to use the dedicated isp on vlan1 as primary. The starlink connection would need to provide internetaccess via vlan5 when active.
- Vlan3 would be the main building with the 2 dedicated isps. These connections would provided connectivity to all of the camp if necessary via vlan5.
I can mange the load ballancing of the WAN connections. The wireless bridges are already in place and configured this is all working. I think I can manage the configuration of the vlans. I am just worried about the interconnectivy, truncs, of the vlans and pushing the traffic in both ways from each physical location. Can I get by with a SG2210P at each location or am I going to need something that is a true layer 3 switch.
