• To modify the IPv4 partition after modifying the ip-route-default-vrf value:
device(config)# system-max ip-route 10000
ip-route and ip6-route values changed.
ip-route: 10000
ip6-route: 1408
Warning: Please reconfigure system-max for ip-route-default-vrf and ip-route-vrf (if required).
Reload required. Please write memory and then reload or power cycle.

This step also
modies the ip6-route system-max parameter and is intended only for the ICX 6610, the ICX 6650, and the FCX series
(not the ICX 7250, ICX 7450, or ICX 7750).
• To allocate 500 routes for IPv4 user-VRF:
device(config)# system-max ip-route-vrf 500
Reload required. Please write memory and then reload or power cycle.
device#
• To allocate 2 x 500 routes for IPv6 user-VRF (1408 - (500+500) = 408):
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#
• To allocate 500 routes for IPv6 user-VRF:
device# system-max ip6-route-vrf 500
Reload required. Please write memory and then reload or power cycle.

• To save the
conguration changes:
device# write memory

Flash to Flash Done.
• After the system reloads, the system-max
conguration appears as an active conguration.

Additional features to support Multi-VRF
In addition to basic features, you can
congure dynamic ARP inspection, DHCP snooping, and IP Source Guard to support Multi-VRF.
Static ARP
Static ARP entries help ensure Layer 2 to Layer 3 mappings. This removes some network overhead in the form of ARP requests and
replies and can be helpful in managing Multi-VRF networks where devices must communicate on a regular basis. The interface
