Your Support Please

Hi all …

I use 3 Mikrotik … i have 3 Fixex Router " same vendor " … i have 1 4g router
This is my topology
00000000000000000000000000.png
i use all Mikrotiks only to protect my servers … because my fixed vendor sometime down … all 3 fixed routers down in the same time
i protect my servers via the 4G router

i make the sane configuration in all Mikrotiks

/ip route
add check-gateway=ping comment=“Primary Default Route - Midco” distance=1 gateway=8.8.4.4
add check-gateway=ping comment=“Backup Default Route - Midco” distance=2 gateway=192.168.8.1
add comment=“Validate Route” distance=1 dst-address=8.8.4.4/32 gateway=192.168.1.1 scope=10

The Problem Is : When the 3 fixed routers down the Mikrotik1 switch to 4G router and Mikrotik2 did not … after seconds Mikrotik2 switch to 4G router and Mikrotik1 do not … and the loop continue
What is the problem ???
Please i want your support

Okay so the 4G router is only capable of hosting ONE WANIP and therefore if more than two of your fixed routers are not available and (if they are from the same ISP, its likely that all three will go down at the same time), you are screwed…

In other words, what you need is to a. get at least three public WANIPs from 4G providers or what I would do if possible.

USE ONE MT ROUTER FOR ALL THREE NETWORKS
HAVE A SECOND DIFFERENT ISP AS A FIRST LINE BACK UP
USE THE 4G HAS THIRD LINE BACKUP.

That way all three networks have a primary back up and a secondary backup.
Normally I would not necessarily recommend a primary backkup and would just go with 4G but you are saying your primary ISP is not very reliable.
IN fact I would say if you can access another ISP make that your Primary and the flaky one your backup or drop them entirely and just use 4G as backup .

Unless you have good reasons, all networks can be behind a single router.

Every fixed router have a Separated no of GiG’s per month … i can not Aggregate them

an i can not get another 4G router … it is very expensive
after your support i go to my 4G router an i show history and i found … all my server’s have the same ip on the 4G router … this is the main problem
how can i forced my server’s to get different IP from 4G router via switch ???

if i make the backup via wifi from mikrotik …it solve the problem ??

It sounds like you have duplicate MACs or IPs connected to the switch.

Will it be possible to post config of all 3 Mikrotiks here:
/export file=MT1 hide-sensitive
/export file=MT2 hide-sensitive

I am sorry … i can not find this menu in Mikrotik ???
Can i config Mikrotik to receive wifi signal and make it for backup ???

Connect to the MikroTik and open the Terminal Window. Then you run this command:
/export compact hide-sensitive file=MyFile.rsc
Then you can open the “Files” menu option and download the file.
