Normal traffic flow without resilient hashing
Traffic flow with resilient hashing enabled
When you enable resilient hashing for ECMP groups, the flow-map table is created with 64 paths (the OS10 default maximum
number of ECMP paths) and traffic is equally distributed. In the following example, traffic 1 maps to next hop 'A'; traffic 2 maps
to next hop 'C'; and traffic 3 maps to next hop 'B.'
Member link goes down
In the following example, if member link D goes down, resilient hashing distributes the traffic intended for member link D to A
and B. The existing 1, 2, and 3 traffic is not disturbed.
