Applicable Environment
If two hosts on different network segments are not configured with the default gateways, you
can enable routed proxy ARP to on a routing device connecting the two hosts to resolve IP
addresses between the two hosts.
Pre-configuration Tasks
Before configuring routed proxy ARP, complete the following tasks:
l Connecting interfaces and setting physical parameters for the interfaces to ensure that the
physical layer status of the interfaces is Up
l Setting link layer protocol parameters for interfaces to ensure that the link layer protocol
status on the interfaces is Up
Data Preparation
To configure routed proxy ARP, you need the following data.
No. Data
1 Number of the interface where routed proxy ARP is to be enabled
2 IP address of the interface where routed proxy ARP is to be enabled
1.5.2 Configuring an IP Addresses for an Interface
The IP address of the interface enabled with routed proxy ARP must be on the same network
segment as the IP address of the connected host on a LAN.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number [.subinterface-number ]
The interface view is displayed.
Routed proxy ARP can be enabled on Ethernet interfaces, Ethernet sub-interfaces, VE interfaces,
Eth-Trunk interfaces, Eth-Trunk sub-interfaces, and VLANIF interfaces. The preceding
interfaces and sub-interfaces are Layer 3 interfaces and sub-interfaces.
Step 3 Run:
ip address ip-address { mask | mask-length }
An IP address is configured for the interface.
The IP address of the interface enabled with routed proxy ARP must be on the same network
segment as the IP address of the connected host on a LAN.
