    I'm trying to work on a layer 3 vpn lab with vMX 17.1.R1.8. I get this error message when I'm trying to add an interface to a routing instance:


    [edit routing-instances VPN_K interface]
    RT Instance: Only loopback interface is supported under vrf routing instances in triton mode.
    error: configuration check-out failed


    According to the links below the problem is that I have the wrong network service mode configured.




    I've changed this to ip as you can see here:

    root> show configuration chassis
    fpc 0 {
    network-services ip;


    But, when I do show chassis network-services I still see the mode as ethernet (I have rebooted).


    root> show chassis network-services
    Network Services Mode: Ethernet


    Is being unable to change the network services mode a limitation of vMX or have I done something wrong?

    The BASE License that comes with vMX only runs in enhanced-ethernet mode.  You need to apply an ADVANCED or PREMIUM license to get enhanced-ip to work.


    If you have purchased ADVANCED or PREMIUM license, load it with "request system license add"


    There is a free 60 day premium license located on juniper.net https://www.juniper.net/us/en/dm/free-vmx-trial/.

    Applying the trial license fixed the problem. Thanks a lot.
