Let me first start by saying that I am the network admin for a Wisp and we have recently switch to a mikrotik as our main router and it is quite possibly the most amazing routing software that i have ever seen. I first would like to apologize for my ignorance and give a little back ground as to why i do no know much about mikrotik. I am 22, a Full-Time Electrical Engineering Technology major as well as a Full time Network admin for a small wisp in OK. We do not have the funds or the time to send me to a mikrotik certification course (although i would love to).

Now for my situation. I will be installing two Wireless links at a Customers location (for redundancy) and i want to use a mikrotik router to monitor the status of each link. I want to use ARP monitoring to verify the status of each link. Most of the threads i find talk about using ARP monitoring in conjunction with interface bonding which requires having a mikrotik router on the customer's side of the links as well as our side of the links. Im not quite sure how i should set this up. This is basically what i want to accomplish.

(customer side)
link 1 = 192.168.1.5
link 2 = 192.168.1.4
mikrotik router = 192.168.1.3 <----- do the monitoring
subnet = 255.255.255.0
gateway = 192.168.1.1

(WISP side)
link 1 = 192.168.1.7
link 2 = 192.168.1.6

(On the wisp side the links will run into a switch which then will run to our Main mikrotik router)
This is my logic for thinking how it should work

if ( link 1 = up)
use link 1
else
use link 2

I am not even sure where to begin, so any help would be awesome. I apologize if this is a duplicate thread and if so if you could just direct me to the correct post it would be greatly appreciated.

Steps..

1) Make 2 P2P transparent Link.
2) Create bonding interface and add the 2 Ethernet interface of the link. http://wiki.mikrotik.com/wiki/Manual:Bonding_Examples
3) Assign IP address to each bonding interface.
4) Select ARP monitoring and under the target ip , assign the bonding interface ip of the other side router.

Is it necessary to have two a router on either end of the wireless links?
