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 WX switch in a remote Mobility Domain. The WX switch forwards
the user traffic by creating a VLAN tunnel to a WX switch 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 WX
switch that the user accesses forms a tunnel to a WX switch at the user’s
home site.
Figure 4 illustrates a sample Network Domain configuration consisting of
Mobility Domains at six sites connected over a WAN link.
