    hi all

    What is the defaul load-balance behavior for LAG on MX switch? Is a routing policy statement  with a load-balance per-packet action is explicitly needed to be configured on the forwarding-table or not ?

    Hi,

     

    By default, MX uses below parameters for different family in HASH calculation on MPC while load-balancing on ae bundle. You don't need explicit config of " load-balance per-packet " for ae.

     

    Note: The one highlighted is GRAY are not user configurable.
