Layer-3 Mobility Overview
W-IAPs form a single Instant network when they are in the same Layer-2 (L2) domain. As the number of clients
increase, multiple subnets are required to avoid broadcast overhead. In such a scenario, a client must be
allowed to roam away from the Instant network to which it first connected (home network) to another
network supporting the same WLAN access parameters (foreign network) and continue its existing sessions.
Layer-3 (L3) mobility allows a client to roam without losing its IP address and sessions. If WLAN access
parameters are the same across these networks, clients connected to W-IAPs in a given Instant network can
roam to APs in a foreign Instant network and continue their existing sessions. Clients roaming across these
networks are able to continue using their IP addresses after roaming. You can configure a list of Virtual
Controller IP addresses across which L3 mobility is supported.
The Dell Networking W-Series Instant Layer-3 mobility solution defines a Mobility Domain as a set of Instant
networks, with the same WLAN access parameters, across which client roaming is supported. The Instant
network to which the client first connects is called its home network. When the client roams to a foreign
network, an AP in the home network (home AP) anchors all traffic to or from this client. The AP to which the
client is connected in the foreign network (foreign AP) tunnels all client traffic to or from the home AP through
a GRE tunnel.
