Configuring Layer 3 Mobility
You must complete these tasks to configure Layer 3 mobility:
1. Configure Layer 3 mobility settings for the local Wireless Edge Services zl
Module:
• IP address
• WLANs on which Layer 3 mobility is enabled
2. Specify the peers’ IP addresses.
3. Enable Layer 3 mobility.
4. Save the configuration and complete these steps on all other Wireless Edge
Services zl Modules in the Layer 3 mobility domain.
It is assumed that you have completed the configurations outlined in Table 9-2.
Note You cannot use user-based, or dynamic, VLANs in a WLAN assigned to the Layer 3
mobility domain. In other words, the Dynamic Assignment box in the WLAN’s Edit
screen must be unchecked.
