Port Configurations


MSK-IX operates an Ethernet network supporting VLAN tagging in accordance with IEEE 802.1Q standard. In each location (city of presence), the following types of VLANs are supported:

  • Common (peering) VLAN is used for establishing peering sessions between participants via a Route Server or on bilateral basis. A most common service for new participants.

  • Private VLAN (Layer 2 VPN) is used for isolating traffic between ports allocated to one or more participants.

  • Multicast VLAN is used for data transmission via multicast protocols.

  • Quarantine VLAN is used for testing and configuration debugging purposes when connecting to MSK-IX.


MSK-IX supports the following port configurations:

  • Untagged port. Default configuration for accessing one VLAN via one physical interface.

  • Trunk port. Access to multiple VLANs via one physical interface.

  • Q-in-Q tunneling. Allows a Layer 2 Ethernet connection between two customer interfaces on MSK-IX network by encapsulating one 802.1Q trunk inside another.

  • LACP Etherchannel. Allows multiple physical interfaces to combine into one logical channel.

  1. Trunk ports in Moscow and in St. Petersburg can only be used to simultaneously access Common (peering) VLANs in the two cities with the MIX service .

  2. Q-in-Q is only allowed on untagged ports configured into private VLANs.

Please note:
    1. If you wish to use interfaces other that listed above, please consult with MSK-IX technical representatives.

    2. Сustomer equipment connected to MSK-IX must have FAC certification in Russian Federation.

    3. The possibility to connect at 40 Gbps must first be confirmed by MSK-IX administrative representatives.
