Proxy ARP Classification
Proxy ARP is classified into the following types: routed proxy ARP, intra-VLAN proxy ARP, and inter-VLAN Proxy ARP. Table 1 describes the usage scenarios.
Proxy ARP Type | Scenario |
|---|---|
Routed Proxy ARP | Hosts that need to communicate and are not configured with default gateways belong to the same network segment but different physical networks (different broadcast domains). |
Intra-VLAN Proxy ARP | Hosts that need to communicate belong to the same network segment and VLAN but port isolation is configured in the VLAN. |
Inter-VLAN Proxy ARP | Hosts that need to communicate belong to the same network segment but different VLANs. |
Routed Proxy ARP
# Configure IP address 172.16.1.1/24 on VLANIF 100 and enable routed proxy ARP.
<HUAWEI> system-view
[HUAWEI] vlan batch 100
[HUAWEI] interface vlanif 100
[HUAWEI-Vlanif100] ip address 172.16.1.1 24
[HUAWEI-Vlanif100] arp-proxy enable
Intra-VLAN Proxy ARP
# Configure IP address 172.16.1.1/24 on VLANIF 100 and enable intra-VLAN proxy ARP.
<HUAWEI> system-view
[HUAWEI] vlan batch 100

[HUAWEI-Vlanif100] arp-proxy inner-sub-vlan-proxy enable
Inter-VLAN Proxy ARP
# Configure IP address 172.16.1.1/24 on VLANIF 100 and enable inter-VLAN proxy ARP.
