Configuration example
Network requirements
As shown in Figure 208, the IP and MAC addresses of Host A are 10.1.1.2 and 000f-e349-1233, respectively. The IP and MAC addresses of Host B are 10.1.1.3 and 000f-e349-1234, respectively.
Configure ARP filtering on GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 of Router B to permit ARP packets from only Host A and Host B.
Figure 203: Network diagram
Configuration procedure
# Configure ARP filtering on Router B.
<RouterB> system-view [RouterB] interface gigabitethernet 1/0/1 [RouterB-GigabitEthernet1/0/1] arp filter binding 10.1.1.2 000f-e349-1233 [RouterB-GigabitEthernet1/0/1] quit [RouterB] interface gigabitethernet 1/0/2 [RouterB-GigabitEthernet1/0/2] arp filter binding 10.1.1.3 000f-e349-1234
Verifying the configuration
# Verify that GigabitEthernet 1/0/1 permits ARP packets from Host A and discards other ARP packets.
# Verify that GigabitEthernet 1/0/2 permits ARP packets from Host B and discards other ARP packets.
