Compatibility Cisco Rapid-PVST and Juniper EX MSTP

    Hi guys,

    just a short question.

    Lets assume we have a Cisco Catalyst running STP Version Rpaid-PVST and now connect a Juniper EX-Switch running MSTP.

    The MSTP is configured to have 3 Instances -> CIST / MSTI1 / MSTI2

     

    Will these STP-Versions be compatible (and if yes, which STP-Version will it be), or are these STP-Versions incompatible and the switches will run as "standalone"-Boxes and the Cisco and the Juniper-Switch will be a root-bridge for themselves ?

     

    Thank you so much,

    Christoph
