Layer 3 Roaming
Save
Layer 3 Roaming allows devices to maintain their IP addresses and network connectivity as they move between different access points on a wireless network. This is in contrast to Layer 2 roaming, where devices must re-associate with each new access point, which can cause interruptions in service.
Benefits of Layer 3 Roaming
Layer 3 roaming offers several advantages over Layer 2 roaming, including:
- Seamless connectivity: Devices can move between access points without losing their connection, ensuring a consistent user experience.
- Reduced latency: By avoiding the need for re-association, Layer 3 roaming can reduce latency and improve overall network performance.
- Improved security: Layer 3 roaming can help to improve security by preventing devices from being disconnected from the network as they move between access points.
How Layer 3 Roaming Works
Layer 3 roaming relies on a number of protocols to manage the transfer of devices between access points. These protocols include:

How Layer 3 Roaming Works
Layer 3 roaming relies on a number of protocols to manage the transfer of devices between access points. These protocols include:
- Mobile IP (MIP): MIP is a protocol that allows devices to maintain their IP addresses as they move between networks.
- Proxy Mobile IPv6 (PMIPv6): PMIPv6 is a newer version of MIP that is designed for IPv6 networks.
- Home Agent (HA): The HA is a device that acts as a home base for devices that are roaming.
- Foreign Agent (FA): The FA is a device that acts as a gateway between the device and the HA.
Applications of Layer 3 Roaming
Layer 3 roaming is used in a variety of applications, including:
- Enterprise networks: Layer 3 roaming can be used in enterprise networks to provide seamless connectivity for devices that are moving between different offices or buildings.
