VRF-related System-Max Values
The default FastIron configuration does not allow space for VRF routing tables. As a result, you must modify VRF-related system-max values before configuring a VRF instance. The following table lists commands that configure system-max values at the global level.

system-max Values
For the IPv4 partition, the default value for IPv4 TCAM allocation is decreased to 10,000. IPv6 TCAM allocation can then be increased from the default value of 908 to 1408. Both IPv4 and IPv6 VRF instances are planned to allocate 500 routes each.
The following table lists the
ip-vrf configuration limits for the
system-max command, by line card and platform.

The following table lists
ip-route and ip6-route configuration limits
for the system-max command for ICX 7150 devices. Values vary
depending on the IPv6 prefix length.

The following examples illustrate the system-max values to
support two VRF instances for IPv4 and two instances for IPv6:
device(config)# system-max ip-route-default-vrf 9000 Total max configured ipv4 routes are 12000 - Max ipv4 routes configured for default VRF are 9000 - Max ipv4 routes available for all non-default VRFs are 3000 Warning: Please revalidate these values to be valid for your configuration. Reload required. Please write memory and then reload or power cycle. device#
device(config)# system-max ip6-route-default-vrf 408 Total max configured ipv6 routes are 1408 - Max ipv6 routes configured for default VRF are 408 - Max ipv6 routes available for all non-default VRFs are 1000 Warning: Please revalidate these values to be valid for your configuration. Reload required. Please write memory and then reload or power cycle. device#
device# system-max ip6-route-vrf 500 Reload required. Please write memory and then reload or power cycle. device# end
