5.6 Configuring GRE Tunnels

Tunneling involves encapsulating a packet that supports one protocol within another packet, which may run
on the same protocol or on a different protocol. It is generally used to support evolving networks, its capacity
and security requirements. Generic Routing Encapsulation (GRE) is one of the many commonly used protocols
for IP over IP tunneling.

IP Tunneling allows network designers to implement policies like:

• Assigning routes to different types of traffic

MU MAC

Displays the factory hardcoded MAC address of the MU. This value is set at the factory and
cannot be modified. Thus, it should be consistent as the MU roams within the mobility
domain.

MU IP Addr

Displays the IP address the MU is using within the mobility domain. Again, this may not be
the IP address used by the MU for initial association with the switch, but it is the IP address
set for the MU to roam amongst subnets. For more information, see Configuring Layer 3
Mobility on page 5-35
.

Home Sw IP

Displays the MU’s home switch IP address. This is the IP address of the switch the MU is
initially associated with, before roaming across subnets as part of its layer 3 mobility activity.

Home Sw VLAN

Displays the MU’s home switch VLAN identifier. This is the VLAN index value set for the MU
when it was originally configured as part of a VLAN with its home switch.

Curr Sw IP

Displays the IP address of the switch the MU is currently associated to within the mobility
domain.

Roam

Displays the number of times the MU has roamed to a different layer 3 subnet.
