Fast Layer 2 Roaming and Layer 3 Mobility
Configuring Layer 3 Mobility
Configuring Layer 3 Mobility Settings
The first step in establishing a Layer 3 mobility domain is configuring local Layer 3
mobility settings on your Wireless Edge Services zl Module. You must specify:
■ the IP address that the module uses in the mobility domain:
• an IP address configured on the local Wireless Edge Services zl Module
• an IP address reachable by all peers
In other words, the VLAN with this IP address must be tagged on the
module’s uplink port. Network infrastructure devices must also be able to
route to this address.
■ the local WLANs that can use Layer 3 roaming
Stations do not roam between these WLANs. Stations only roam between RPs
that support the same WLAN. Wireless Edge Services zl Modules create a
separate Layer 3 mobility domain for each WLAN.
To configure the Layer 3 mobility settings, complete these steps:
1. Select Network Setup > Layer 3 Mobility > Configuration.
