Dell PowerConnect M6220 - Proxy Address Resolution Protocol (ARP)

66 Routing Configuration
Specify the IP address that the virtual router function will recognize.
console(config-if-vlan60)#ip vrrp 20 ip 192.150.2.1
Set the priority for the port. The default priority is 100.
console(config-if-vlan60)#ip vrrp 20 priority 254
Enable VRRP on the port.
console(config-if-vlan60)#ip vrrp 20 mode
console(config-if-vlan60)#exit
Using the Web Interface to Configure VRRP
Use the following screens to perform the same configuration using the Graphical User Interface:
• Routing > IP > Configuration. To enable routing for the switch.
•
Routing > IP > Interface Configuration. To enable routing for the VLAN interfaces and configure
their IP addresses and subnet masks.
•
Routing > VRRP > VRRP Configuration. To enable VRRP for the switch
•
Routing > VRRP > Virtual Router Configuration. To configure the interface for VRRP.
Proxy Address Resolution Protocol (ARP)
This section describes the Proxy Address Resolution Protocol (ARP) feature.
Overview
• Proxy ARP allows a router to answer ARP requests where the target IP address is not the router itself
but a destination that the router can reach.
• If a host does not know the default gateway, proxy ARP can learn the first hop.
• Machines in one physical network appear to be part of another logical network.
• Without proxy ARP, a router responds to an ARP request only if the target IP address is an address
configured on the interface where the ARP request arrived.
CLI Examples
The following are examples of the commands used in the proxy ARP feature.
Example #1: Enabling Proxy ARP
To enable IP Proxy ARP:
console#config
console(config)#interface vlan 50
console(config-if-vlan50)#ip proxy-arp
console(config-if-vlan50)#exit
