VR-Mgmt
    This virtual router is
        part of the embedded system in Extreme Networks switches. VR-Mgmt enables remote management
        stations to access the switch through Telnet, SSH, or SNMP sessions; and it owns the
        management port. The management port cannot be deleted from this VR, and no other ports can
        be added. The Mgmt VLAN is created VR-Mgmt, and it cannot be deleted; you cannot add or
        delete any other VLANs or any routing protocols to this VR. (Referred to as VR-0 in earlier
        ExtremeXOS software versions.)
