    Description

    Customize Route Table Attachment

    Enables custom route tables when set to On.

    From the Select Route Tables dropdown menu, select the custom route table(s) to attach to this Spoke Gateway.

    Max Performance

    Creates the maximum number of High Performance Encryption (HPE) tunnels for the Transit-to-Spoke attachment when set to On. The number of tunnels that are created depends on the gateway instance sizes.

    • Max Performance option is valid only when both the Spoke and Transit Gateways are launched with HPE enabled and are in the same cloud type.

    • When the Spoke and Transit Gateways are launched in different cloud types, only one tunnel is created (even when HPE is enabled for both the Spoke and Transit Gateway).

    If Max Performance is Off, only one tunnel is created (even when HPE is enabled for both the Spoke and Transit Gateway).

    To switch between multiple tunnels or one tunnel, detach and reattach the Spoke Gateway to the Transit Gateway.
