    Direct Connect connects Tencent Cloud with the user IDC with a dedicated physical line. After configuring the Direct Connect gateway and dedicated tunnel on the Tencent Cloud side, users need to configure routes on the local IDC. Using the layer-3 sub-interfaces to connect to Tencent Cloud is recommended.


    This document only introduces the local routing configurations associated with Tencent Cloud Direct Connect. For other information, please see the local router documentation or consult your router provider.

    Routing Configuration


    It's recommended that you use the default configurations of Keepalive and holdtime for the BGP connection between the two peers. The holdtime is three times the interval at which keepalive messages are sent. The recommended holdtime value is 180s.
