PPPoE: Peer is not responding

RouterOS General
1

It’s imposible to use pppoe server on mikrotik. Sometimes sessions began to terminate without any reasons:

Using LAN Connection with Intel Gigabit NICs without any network errors.
Two mikrotik servers 5.14 and 5.18 each with ~250 sessions, ~200MBit traffic(up+down) per server, every week randomly in the evening we have such issues.
Third Cisco PPPoE server in the network working without any issues.

/ppp profile print
Flags: * - default 
 0 * name="default" local-address=87.249.XX.XX use-mpls=default use-compression=no use-vj-compression=no 
     only-one=default change-tcp-mss=no incoming-filter="" outgoing-filter="" address-list="" 
/interface pppoe-server server print
Flags: X - disabled

     keepalive-timeout=10 one-session-per-host=yes max-sessions=0 default-profile=default

     keepalive-timeout=10 one-session-per-host=yes max-sessions=0 default-profile=default

Any workaround? Seems that problem exists for years in RoS pppoe module.
Increased ppp keep-alive to 30 seconds, will see whats changed.

Hello my friend
i have 5000 active PPPOE session on Mikrotik without any problem.
peer not responding log usually happen when client have low bandwidth or error.
and i have a question.are you upgrade your router? and what license you use?

3

Increase Keepalive Timeout to 30 seconds in PPPoE server profile.

4

Hi,

is that work ? I have same problem also.

Thanks.

hi all

i am also facing same problem, i am using 5.20 version, log : peer is not responding
in PPPoE all users are disconnecting, i have increase the keepalive time 30sec,
even though my problem is not solved.

can any one of who experience or solved the same please help me to come out of this problem

Great to know that you have 5000 active PPPoE Sessions. May I know how many router are you using and the model numbers please???

I’ve run into the same issue. Adding a third PPPOE client interface means the line connects and immediately disconnects with the log entries ‘initializing’, ‘connecting’, ‘terminating… - hungup’, ‘disconnected’ all with the same timestamp. This appears to be a major bug.

The reply above with 5000 active sessions must be referring to the server PPPOE interface, not a client one (unless Mikrotik make some 5000 port routers they’ve kept very quiet!).

I also am facing this issue, Please help, I have tried almost everything i could i.e.

  1. Changed Switch at client end
  2. Reconfigured Access Point - Station network
  3. WDS Station Bridge mode and Psuedo bridge mode
  4. Dialing only one connection per switch
  5. Increasing time out to 30
  6. Checking Each Customer MAC address for duplication.

Not helped at all, sometimes all my customers get auto disconnected with the same error.

I have attached screenshot of current Logs and My Network Structure, Please help i am in very urgent need of solution

“Peer not responding messages” indicate that server has not received packets from client side for a while. Keepalive is taken into account on such cases. You can increase keepalive but if that does not help, you should figure out what is causing client to not respond to server. For example, unstable ethernet connection between server and client.

11

It looks like the cause of my issue might be a different bug, but as I’ve already posted in this thread, I thought I’d talk through how I fixed it.

I wiped the router, then rebuilt the config from scratch. Line three still played up, but I disconnected two other lines and brought up the third, then the first and the second and all seemed well, even on a reboot. The bug appears to manifest itself the very first time a PPPOE line is brought up when there are already two others running.

The second gotcha is that, when you create the rulesets for the lines, the Mikrotik router now creates rules 0, 1, 1, 2, 3 and seems to ignore the second rule 1. There is no way of editing this, so you need to delete the last three rules and it seems to manage to count the rule numbers correctly the second time you enter them. Seen this issue twice now, so it wasn’t a one-off.

I have the same problem.
I have very good links all my CCQ between 98 and 100% very good transferability and in had in my network that change to many clients to IP Statica tied by mac address to work with more stability.

It got solved i guess,
I changed MTU and MRU to 1504 (1464 i was actually able to ping without fragmenting the packet + 40 of Packet header)
MRRU I set to 1580 (I don’t know how to calculate this but i read somewhere on the internet so set this)

I changed above values for

  1. pppoe sever
  2. All my AP’s and Stations (Under network tab - I am using mostly ubnt devices airgrid and powerbeams)
  3. Client Routers

Issue solved for me, will update if happens again

You can use following command to check fragmentation of packet
ping google.com -f -l 1480

it;s small L not I
