(1) Simplify the routing table entries or static ARP table entries

(2) Configure the working mode of the interface according to the actual situation

The device generates a host route when it learns an ARP entry from a network-side port. To save hardware resources, you can specify a port that connects to a user terminal as a customer-side port. The device will not generate a host route for the learned ARP entry of the user terminal.

Configure the interface as a customer-side port

[H3C-interface]arp mode uni

NNI: When the interface is connected to the network device, it needs to be configured as a network-side interface. The ARP entries learned on this interface can be associated with the routing information on the device and can be used as the next hop for routing information. (Default mode)

UNI: When the interface is connected to the terminal host, it can be configured as a user-side interface. The ARP entries learned on this type of interface are no longer associated with the routing information on the device.
