Usage Guidelines

Usage Scenario

If two hosts are within the same isolate-user-VLAN, communication between them on the Layer 2 network cannot be implemented. In this case, run the arp-proxy inner-sub-vlan-proxy enable command on the associated VLAN interface to enable intra-VLAN proxy ARP. This configuration implements communication between the hosts within an isolate-user-VLAN.

Prerequisites

Hosts that require communication are within the same VLAN, and it is an isolate-user-VLAN.

Example

# Enable intra-VLAN proxy ARP on a VLANIF interface.

<HUAWEI> system-view
[~HUAWEI] vlan 20
[*HUAWEI-vlan20] quit
[*HUAWEI] interface vlanif 20
[*HUAWEI-vlanif20] arp-proxy inner-sub-vlan-proxy enable
