WISP Switch fiber/cat5e

I'm going to need to order some equipment and while I "think" what I'm going to ask would work I figure I'd at least post the question and see if I missed something.


SETUP
Two (2) ERX-SFP routers running VRRP (duplicate configuration) in building
One (1) WS-6-MINI in building - each router connects to switch.

I need two (2) WS-8-150-DC switches running at a remote location and will run conduit/fiber/cat5e/power to the location of the switches (200' distance outdoors)


I will connect each switch to a router with fiber
ERX 1 SFP module <-- fiber cable --> WS Switch 1
ERX 2 SFP module <-- fiber cable --> WS Switch 2


I would then connect each remote switch to the locale switch with cat5e
WS-6-MINI eth ports to WS Switch1 eth port
WS-6-MINI eth ports to WS Switch2 eth port


The thought behind running both fiber and cat5e is strictly for redundancy as this location is fairly remote and difficult to get to.

With the fiber connections you have direct access to A ROUTER, but if fails you have no path to other router, but you are not affected if the building switch fails.

With the cat5e connections from the switches to the local switch you can access the building and the alternate router should one fail.



The goal is to create redundancy where a single equipment failure is not going to take everything offline.

Let me add a diagram here to illustrate what I'm talking about.

There are two ERX routers using VRRP - each router is connected to one switch, the goal is to provide redundancy in case on of the routers fails.

Option 1 is to use the second SPF port in each switch to connect them to each other- thereby allowing traffic to flow back to the working router.
Option 2 is to put a WS-6-MINI switch and connect the two routers to each other - and then run a cat5 cable out to each switch.

It feels like either option would work but I'd appreciate some feedback as to whether or not I'm missing something in the setup that would cause a problem or routing issue.

Thanks

Better test a lot VRRP on edgerouter. I remove it from my setup since it was not as reliable as I would like.

A other problem with VRRP is that the're no link between interface. If LAN is down but WAN is up, you could have the WAN active on one router and the LAN active on a other.

Redundancy can often lead to more problems that the chance of a hardware failure.

Also, I can't see your diagram.

Tryed with FF and Chrome. Same thing, it's only show icone, a round with a bar through it in the middle (left to right). I think it's meen a blocked plugin or something like that.

IE and Edge both show a broken image logo.
