Configuring VRF system-max values

Use this example procedure to modify the default system-max values to accommodate Multi-VRF on a RUCKUS ICX 7450.

The default system-max value must be configured because the device does not have routing table space for user VRFs.

In this example, two user VRFs are configured with 512 maximum routes on each VRF. The ip-route-default-vrf and ip-route-vrf values must be modified. The write memory and reload commands are required after the modification.

Once the device has rebooted after the reload, enter the show default values command to display the system-max settings.

  1. Verify the default values.
    device(config)# show default values
    sys log buffers:50         mac age time:300 sec       telnet sessions:5
    ip arp age:10 min          bootp relay max hops:4     ip ttl:64 hops
    ip addr per intf:24
                  :
                  :
    System Parameters    Default    Maximum    Current    Configured
    ip-arp               4000       64000      4000       4000
    ip-static-arp        512        6000       512        512

    ip-route             12000      15168      12000      12000   
    ip-static-route      64         2048       64         64
                  :
                  :
    ip-vrf               16         16         16         16
    ip-route-default-vrf 12000      15168      12000      12000    
    ip6-route            5120       5120       5120       5120

    device(config)#
    
  2. Change the maximum number of routes, save the configuration, and reload the device.
    device(config)# system-max ip-route-default-vrf 10000
    Total max configured ipv4 routes are 12000
      - Max ipv4 routes configured for default VRF are 10000
      - Max ipv4 routes available for all non-default VRFs are 2000
    Warning: Please revalidate these values to be valid for your configuration.
    Reload required.  Please write memory and then reload or power cycle.
    device(config)#
    device(config)# system-max ip-route-vrf 512
    Reload required.  Please write memory and then reload or power cycle.
    device(config)#
    device(config)# exit
    device# write memory
    Write startup-config done.
    device# reload
    Are you sure? (enter 'y' or 'n'): Rebooting(0)...

  3. Confirm the modified values.
    device(config)# show default values
    sys log buffers:50         mac age time:300 sec       telnet sessions:5
    ip arp age:10 min          bootp relay max hops:4     ip ttl:64 hops
    ip addr per intf:24
