2 ISP into same network

[AoGeko]

Im looking to provide a fallback internet connection in the event the primary connection drops for a business that requires internet connection 24.7. 

What is the best way to acheieve this? Below is a very crude illustration as to what I am attempting to accomplish. Please enlighten me.

 

Consider the primary as the main connection and the secondary as the fallback connection.

Easiest way would be to put an AD, or administrative distance between the 2 routes so it prefers Route 1 over 2. If route 1 is dead, it should sent over route 2.

Without a router you won't be able to do much.
But you can use protocols like VRRP (if you are not using cisco equipment, if you do you have more options).

Find dual wan router

or you can build pfsense with dual nic

 

Personally I've used both, depend what kind situation you need both can be adjusted for almost every config available.

These what I've used in the past

I don't think you can find old dlink dual wan router.

 

As for TPLink there are cheaper version R470+, and it support 4 WAN

There is definitely a router in between the modem and switch i didnt include in diagram due to space.

If i had a dual wan router i would be able to plug primary and secondary to dual wan and then dual wan into switch?

No, you plug it into each port

ex: ISP 1 WAN Port 1, ISP 2 WAN Port 2

 

You set the connection as round robin, failover, or load balance

I mean Yes, you can plug it into switch to expand

What router is that link referring to? Is there a router you recommend? Ive been searching and see a few from companies Im really not familiar with but would prefer a tp link router.

Do both ISP connections come from the same local exchange and go through the same road side termination points? If so getting two ISP connections may not give you much redundancy other than from ISP level configuration issues.

 

Better to just talk to one ISP and see what they can offer both connection redundancy wise and SLA wise.

A ubiquity edge router can build a redundancy connect from 2 wan sources, it even has a simple wizard to set it up. They also just released 2 new awesome looking routers.
