Configuring Resilient Hashing for Default VRF

Describes the process of configuring Resilient Hashing on the SLX devices.

About this task

Resilient Hashing is available for default VRF as well as user created VRFs. To configure Resilient Hashing on default VRF:

Procedure

  1. Navigate to the Configuration context using the conf term command.
    SLX# conf term
    SLX(config)#
  2. Use the resilient-hash command to configure.
    SLX (config)# resilient-hash ?
    Possible completions:
        ecmp        Resilient hash ECMP
        max-path    Resilient hash max path (8|16|64)
    
    SLX (config)# resilient-hash ecmp ?
    Possible completions:
        enable      Enable resilient hash ECMP
    
    SLX (config)# resilient-hash ecmp enable
  3. Configure the max-path value.

    The default max-path value is 8. You can choose to use 8, 16, or 64 paths.

    SLX (config)# resilient-hash ?
    Possible completions:
        ecmp        Resilient hash ECMP
        max-path    Resilient hash max path (8|16|64)
    
    SLX (config)# resilient-hash max-path 8
    SLX (config)#
  4. Verify the configuration using the show ip route system-summary command.
    SLX # show ip route system-summary
