7.4 Configuring Routed Proxy ARP

This section describes how to configure routed proxy ARP to ensure the interconnection between
different subnets.

7.4.4 Checking the Configuration
7.4.1 Establishing the Configuration Task
Applicable Environment
Two physical networks of an enterprise belong to different subnets of an IP network and are
isolated by a switch. To ensure the interconnection of these two physical networks, you need to
enable proxy ARP on the interfaces connecting the switch and physical networks.
The network IDs of host IP addresses of subnets must be the same, and the hosts do not need to
be configured with the default gateway.
Pre-configuration Tasks
Before configuring routed proxy ARP, complete the following tasks:
7-6
Run the display arp [ all ] command to check all the ARP mapping tables, including static
and dynamic ARP entries.
Run the display arp dynamic [ | { begin | exclude | include } regular-expression ]
command to check the dynamic ARP mapping table.
Run the display arp interface interface-type interface-number [ vid vlan-id ] [ | { begin |
exclude | include } regular-expression ] command to check the ARP mapping table on a
specified interface.
Run the display arp network net-number net-mask [ dynamic | static ] [ | { begin |
exclude | include } regular-expression ] command to check the dynamic ARP mapping
table on a specified network segment.
Run the display arp static [ | { begin | exclude | include } regular-expression ] command
to check the static ARP mapping table.
Run the display arp statistics command to check the statistics on ARP entries, including
the total number of ARP entries, the number of dynamic ARP entries, the number of static
ARP entries, and the number of ARP entries configured on the interface.
Run the display arp vpn-instance vpn-instance-name [ dynamic | static ] [ | { begin |
exclude | include } regular-expression ] command to check the ARP mapping table of a
specified VPN instance.
