Purefiber connect SFP directly to Mikrotik Router

Hi,

I am trying to connect my Mikrotik router directly by plugging in the SFP directly into the router.  I got the PPPoE from the telus whitebox (username: [email protected], password is 6 chars long).  VLAN is 40, priority is 0.  I also set the MAC to the same value that was on the telus whitebox.  I plugged the SFP directly into the mikroik and it shows the link is up.  It also shows it is trying to connect using PPPoE.  It sends one frame over the VLAN, but doesn't get any response.  Without any error other than timeout, this is hard to debug.

Any suggestions?

Thanks,
Bruce

    Hi there
    how i did it on my home set up after I upgraded to 3gps speed is as follows (that way i keep TV working without any issues as well)
    ONT 10g port to my ASUS 10g port

    -on the ASUS

    • I bridged port 1 (the 2nd blue port that can be used as wan aggregator)
    • i enabled IGMP proxy under LAN, disabled airprotection and all QoS (it messes with multicast frames sadly)
      below info is irrelevant, plug in what you need
    • port 2 has a 24 cisco
    • port 3 has a switch for my servers SFPs
    • port 4 gaming pc

    back to relevant info: on the telus hub

    • Telus hub to the bridged port
    • telus AP in bridged mode(it should be the default)
    • i factory reset the telus hub - i had a lot of custom touches on it

    now the ONT sees 2 devices coming to the 10g port, one is my asus router one is the telus hub. Telus hub and AP handle my security system and wireless STBs without an issue

    both routers are on DHCP leases from the ISP, no PPoE
    Everything works as intended.

    Hi,

    I confirmed the PPPoE creds are good by setting the telus whitebox in bridge mode on the 10G port.  On the Mikrotik, I changed the PPPoE client interface from SFP to ether1 which is connected to the telus whitebox 10G port.

    Thanks,
    Bruce

        TELUS_Support​,

        Sorry, no resolution yet.  I don't think I am going to get much further without insights or debug/stats from the Telus equipment side.  On my end, the counters and PPPoE state machine indicate the PPPoE discovery phase is started, but I don't see any response from the Telus side.  I do plan to spend some quality time with wireshark looking at my side to see if I see anything out of the ordinary.  Given the PPPoE seems to be working fine (bridge mode) and the SFP gets link up, I am guessing the issue is somewhere in the VLAN and/or PPPoE layer.  VLANs are pretty simple, so I don't expect much to go wrong there, so that leaves PPPoE.

        I did read somewhere that when the Telus whitebox is in bridge mode, the MAC address is substituted or ignored.  As the MAC address is used in the discovery process, this might be where the discovery goes off the rails because I don't see a response. Can TELUS_Support​ elaborate on the client side PPPoE MAC address in both bridge mode and non-bridge mode (e.g. SFP plugged directly into the Mikrotik router)?

        Thanks,
        Bruce
