Usage Guidelines

To allow users in different VLANs to communicate at Layer 3, you must enable inter-VLAN proxy ARP on the interface.

After inter-VLAN proxy ARP is enabled and packets are sent from different VLANs but do not have the corresponding ARP entries, ARP packets are replicated in all VLANs on the involved sub-interface. If a lot of VLANs are configured, a large number of ARP packets need to be replicated, causing heavy burden on the peer device and abnormalities (such as high CPU usage and broadcast suppression) on downstream devices. In addition, the local device may fail to send ARP packets in time due to the replication of a large number of packets, which may lead to ARP learning failures. Therefore, do not configure too many VLANs on an interface.
