Configuring ARP Proxy

Configuring ARP Proxy

Proxy ARP Classification

Proxy ARP is classified into the following types: routed proxy ARP, intra-VLAN proxy ARP, and inter-VLAN Proxy ARP. Table 14-1 describes the usage scenarios.

Table 14-1  Proxy ARP Type

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] interface vlanif 100
[HUAWEI-Vlanif100] ip address 172.16.1.1 24
[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.

<HUAWEI> system-view
[HUAWEI] vlan batch 100
[HUAWEI] interface vlanif 100
[HUAWEI-Vlanif100] ip address 172.16.1.1 24
[HUAWEI-Vlanif100] arp-proxy inter-sub-vlan-proxy enable
