    The em interfaces are used internally to connect the RE to the internal ethernet switchboard. It can't be assigned to a routing interface.
    Information on em interfaces on physical MX devices - https://supportportal.juniper.net/s/article/MX-Internal-interfaces-em0-and-em1-on-MX240-MX480-MX960-explained?language=en_US#:~:text=em0%20is%20the%20interface%20connected,switch%20on%20the%20other%20SCB.

    I thought it only interface em0 and em1 that are only used for this purpose?

    em interfaces are for management purposes (ethernet management)

    Your traffic interfaces are labeled by speed ge, xe or et

    Hi Olalekan,

    Although I have not installed vMX on GNS3.0 yet, can you try reading section 2.2 of the blog https://brezular.com/2022/06/01/juniper-vmx-on-gns3/ and check if it is relevant to your problem? Also, can you check the output of "show chassis fpc pic-status" ?
