LAG default load-balance behavior

‎10-09-2014 09:00 AM

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.
