2.3.2 Configuring Common Static ARP Entries

Static ARP entries are required for the communication between common interfaces.
Context
If static ARP and the Virtual Router Redundancy Protocol (VRRP) are enabled on a device
simultaneously, the virtual IP address of the VRRP backup group configured on the VLANIF
interface cannot be the IP address contained in the static ARP entries; otherwise, incorrect host
routes are generated and thus packets cannot be normally forwarded.
Procedure

For the packets whose destination IP address is on another network segment, static ARP
can help these packets traverse a gateway of the local network segment so that the gateway
can forward the packets to their destination.
When you need to filter out some packets with illegitimate destination IP addresses, static
ARP can bind these illegitimate addresses to a nonexistent MAC address.
