Extreme SLX-OS Layer 3 Routing Configuration Guide, 20.5.1

Navigate to the Configuration context using the conf term command.

SLX# conf term
SLX(config)#

Navigate into the VRF that you want to apply Resilient Hashing to.

SLX (config)# vrf vrf2
SLX (config-vrf-vrf2)# ?
Possible completions:
    address-family Enter Address Family command mode
    describe Display transparent command information
    do Run an operational-mode command
    evpn VRF EVPN config
    exit Exit from current mode
    help Provide help information
    ip VRF specific IP commands
    no Negate a command or set its defaults
    pwd Display current mode path
    rd Configure Route Distinguisher
    resilient-hash Resilient hash
    top Exit to top level and optionally run command
    vpn-statistics VPN Statistics

Use the resilient-hash command to configure.

SLX (config-vrf-vrf2)# resilient-hash ?
Possible completions:
    ecmp        Resilient hash ECMP
    max-path    Resilient hash max path (8|16|64)

SLX (config-vrf-vrf2)# resilient-hash ecmp ?
Possible completions:
    enable      Enable resilient hash ECMP

SLX (config-vrf-vrf2)# resilient-hash ecmp enable
SLX (config-vrf-vrf2)#

Optional: If required, configure the max-path value.

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

SLX (config-vrf-vrf2)# resilient-hash ?
Possible completions:
    ecmp        Resilient hash ECMP
    max-path    Resilient hash max path (8|16|64)

SLX (config-vrf-vrf2)# resilient-hash max-path 8
SLX (config-vrf-vrf2)#

Verify the configuration using the do show run vrf <vrf-name> command.

SLX (config-vrf-vrf2)# do show run vrf vrf2
vrf vrf2
    resilient-hash ecmp enable
    resilient-hash max-path 8 
    address-family ipv4 unicast
    !
!

You can also verify the configuration using the show ip route system-summary command.

SLX (config-vrf-vrf2)# show ip route system-summary
