Configuring network domains
A Network Domain is a group of geographically dispersed Mobility Domains that share information over a WAN link.
This shared information allows a user configured in one Mobility Domain to establish connectivity on a WSS in a
remote Mobility Domain. The WSS forwards the user traffic by creating a VLAN tunnel to a WSS in the remote
Mobility Domain.
About the network domain feature
A Network Domain allows functionality found in Mobility Domains to be extended over a multiple-site installation. A
user configured to be on a VLAN at his or her home site can travel to a remote site, connect to the network, and be
placed in his or her native VLAN. To do this, the WSS that the user accesses forms a tunnel to a WSS at the user’s home
site.
Figure 1 illustrates a sample Network Domain configuration consisting of Mobility Domains at six sites connected over
a WAN link.
