Setting the Tunnel Mode

Setting the Tunnel Mode


By default, the tunnel mode on CE12800 and CE12800E series switches is Virtual Extensible Local Area Network (VXLAN). To use the multicast VPN function, you need to perform this task to change the tunnel mode to GRE.


  1. Run system-view

    The system view is displayed.

  2. Run ip tunnel mode gre

    The tunnel mode is set to GRE.

    By default, the tunnel mode is VXLAN.


    Only the Admin-VS in port mode supports this command, and all VSs in group mode support this command.

  3. Run commit

    The configuration is committed.

Follow-up Procedure

After the command is used in a VS to configure a tunnel mode, restart the VS. After the VS restarts, restart all cards in the VS to make the configuration take effect.
