500 users on two PPPOE server, on same Lan, same fiber line

RouterOS General
1

Good morning everyone. I have a problem that I can not solve:
So far I had 500 clients that authenticated in PPPOE on a routerboard RB110AHx2.
The gateway of the source fiber is 10.0.2.1.
RB1100AHx2 Wan port 10.0.2.100, LAN port 15.15.15.100.
The pool of IP manually check to customers is 172.16.0.2-172.16.3.254 (local area network 172.16.0.1)
In the firewall I set the pool for expired (non-paying customers) with the address class 172.16.4.1-172.16.4.254.
Everything works correctly.
Now I want to add a second RB1100AHx2 to manually divide customers:
250 on the first routerboard and 250 on the second.
In second routerboard I set as the gateway 10.0.2.1 (router fiber).
Wan 10.0.2.101 port, LAN port 15.15.15.101.
Range to be assigned to customers 172.16.6.2-172.16.7.254 (local area network 172.16.6.1)
IP pool for expired (non-paying customers) 172.16.8.1-172.16.8.254.
I copied the customers from “secret” of first routerboard and paste them in the second routerboard, and then I changed for each customer local area network (from 172.16.0.1 to 172.16.6.1, as well as assign each one ip of new range) .
I then disabled the first 250 customers on the first routerboard, and instead enabled the same on the second.
The problem is that of 250 customers, about 150 authenticate themselves regularly on the first routerboard, while 100 “disappear.”
Strangely the 100 that do not authenticated on the first routerboard, I find them in the Log of the second routerboard. These in an attempt to authenticate, return the error “Authentication Error” in the log.
What’s wrong?
In short, I just want to add a second routerboard to divide the customers.
Who can help me?
Please … after so many attempts…I’m desperate …

Have you only one ethernet cable from customers?

If you “share” the cable, the customers can see both PPPoE Servers and where customers autenticate is near random…

If you have more than one source from customers,
you must use radius and user-manager,
the client automatically login on connected PPPoE server.

You can choiche where customers do login “moving” ethernet cables between RB1100AHx2.


P.S.:

I also use one RB1100 as interface for fiber, two RB1100AHx2 for split near 2000 user… (separately two 1200 as NTP1&2/DNS1&2 servers, and one pc for user-manager [one RB1100AHx2 are also used as failover for user-manager])
(and I have another fiber to do the same thing for other near 2000 users)

Ciao rextended. Ho letto che sei italiano… e questo mi semplifica la vita… eheheh.
Puoi spiegarmi meglio come hai risolto tu?
Grazie mille.
