Cisco Cisco Aironet 1200 Access Point Notas de publicación

Five devices participate in proxy Mobile IP:

A visiting client device. The visiting client device is any device such as a personal digital assistant 
or a laptop that can associate to a wireless access point. It does not need any special proxy Mobile 
IP software. 

An access point with proxy Mobile IP enabled. The access point proxies on behalf of the visiting 
client device, performing all mobile IP services for the device. The access point uses a subnet map 
to keep track of home agent information. The access point also gets updates about new home agents 
from the authoritative access point.

An authoritative access point on your network supporting proxy Mobile IP. The authoritative access 
point uses a subnet map to keep track of the home agent information for all visiting client devices.

A home agent. The home agent is a router on the visiting client’s home network that serves as the 
anchor point for communication with the access point and the visiting client. The home agent 
tunnels packets from a correspondent node on the Internet to the visiting client device. 

A foreign agent. The foreign agent is a router on your network that serves as the point of attachment 
for the visiting client device when it is on your network, delivering packets from the home agent to 
the visiting client.
