Fast Layer 2 Roaming and Layer 3 Mobility
Verifying and Managing Layer 3 Mobility
In Figure 9-13, the 10.4.1.30 Wireless Edge Services zl Module is the HM for
three stations associated with the wireless network, and the 10.4.2.30 module
is the HM for one station. However, one of the 10.4.1.30 module’s stations has
roamed to an RP supported by the 10.4.2.30 module. Because these two
modules are on different VLANs, the roam occurred at Layer 3. As you can see
in the top row in Figure 9-13, the station has 10.4.1.30 as its HM, but 10.4.2.30
as its CM; the Roam column has a green check mark.
