Equal cost multi-path

ECMP is a routing technique where next-hop packet forwarding to a single destination occurs over multiple best paths. OS10 uses a hashing algorithm to determine the next-hop when you enable ECMP. The hashing algorithm makes hashing decisions based on values in various packet fields as well as some internal values.

  • Configure the hash algorithm in CONFIGURATION mode.
    hash-algorithm ecmp  
                                           {crc | xor | random}
                                        

Change hash algorithm

OS10(config)# hash-algorithm ecmp crc
