  • 1.  VPLS problems on SRX340

    Posted 05-01-2025 19:33

    Hello i am trying to configure a vpls from mikrotik to srx340 i have gotten to the point where the vpls is up. I wanted to verify that i can ping trough the VPLS but no luck.

    I have vlan 600 inside the VPLS i can see the mac addresses of end devices on both sides but the ping doesnt work.

    Am i missing something?

    here is the vpls configuration:

    instance-type vpls;
    interface ge-0/0/1.600;
    protocols {
        vpls {
            interface ge-0/0/1.600;
            no-tunnel-services;
            vpls-id 23;
            mtu 1400;
            neighbor 192.168.88.4;
        }
    }

    and interface ge-0/0/1.600:

    flexible-vlan-tagging;
    encapsulation flexible-ethernet-services;
    unit 600 {
        encapsulation vlan-vpls;
        vlan-id 600;
        family vpls;
    }

    help is much appreciated

    The VPLS is an isolated mac table for member interfaces.  In the above configuration the SRX is pure layer 2 with the only interface ge-0/0/1.600 as a member locally.  The ping would need to come from a device inbound on that vlan and interface only.

    Hello i have a mikrotik plugged to srx340 ge 0/0/1 on vlan 600 - with ip address on vlan600  192.168.56.1.                   -lets call this router RB1

    On the other end of VPLS i have mikrotik where i terminate vpls on vlan 600 - where i have configured IP address 192.168.56.2.             -lets call this router RB2

    I have noticed that in ip neighbors on RB1 i can see the mac address and ip address of remote RB2, i dont see the ip neighbor on vlan600 but on physical interface of mikrotik.
    On RB2 i cant see any ip neighbor trough VPLS.

    BUT when i look into the ip table i can see mac addrreses of RB1 on RB2 and vice versa.

    If I remember the Mikrotik correctly the RB1 data sounds correct.  To spread the mac information would require setting up the bridge for the vlan.

    I've not used vpls on Mikrotik so not sure how the mac tables are maintained for the RB2 side.

    @Richard Adamec  

    Please, I have the same issue as you, but with VLAN 2040.

    Could you please tell me which Junos version is installed on your device with this configuration?

    Thanks in advance 

    I wait your reply 

    nstance-type vpls;
    interface ge-0/0/1.600;
    protocols {
        vpls {
            interface ge-0/0/1.600;
            no-tunnel-services;
            vpls-id 23;
            mtu 1400;
            neighbor 192.168.88.4;
        }
    }

    and interface ge-0/0/1.600:

    flexible-vlan-tagging;
    encapsulation flexible-ethernet-services;
    unit 600 {
        encapsulation vlan-vpls;
        vlan-id 600;
        family vpls;

    I was recently working on a similar issue on a 1500 but I was not able to make it work with VLAN tagging on the interface. Instead, I had to set the interface to use ethernet-vpls encapsulation and the next hop router past that was just a layer 3 interface. The configuration on the interface would look something like this. Additionally, make sure the global layer2-learning mode is transparent bridge as switching mode seems to be incompatible.
    interface ge-0/0/1.600:
    encapsulation ethernet-vpls;
    unit 600 {
        family vpls;
    }
