    Posted 01-04-2018 00:56

    I tried to change chassis network service to ip instead of ethernet to support Layer 3 VPN. However the vMX keeps ethernet for chassis network service even if I executed "set chassis network-services ip" and rebooted all routing enginee "run request system reboot junos both-routing-engines ". Finally I have to install a temp licence to resolve the problem. However I don't know which exact feature is needed for the feature in vMX. Is it VMX-SCALE? Anyone could tell me? Thanks!

     

    [edit routing-instances vpn-a interface]
    'ge-0/0/1.0'
    RT Instance: Only loopback interface is supported under vrf routing instances in triton mode.

    Hi Folks,

     

    Triton mode refers to "ethernet Services mode" this is configured under the chassis:

    ===============================

    chassis {

        network-services ethernet;

    }

    ===============================

     

    To be able to add interfaces into an L3 VPN routing instance you will

    need to switch to "IP services mode"

    The default IP Services mode provides complete functionality, while the

    Ethernet Services mode only provides support for Layer 2.5 functions.

     

    ===============================

    chassis {

        network-services ip;

    }

    ===============================

     

    Since the "ip" mode is the default you could also simply remove the

    "network-services ethernet" statement.

     

    Here are 2 links on Ethernet Services Mode and its limitations.
