How Mobility Anchoring Works

Now that we’ve established a foundation for Cisco Wireless Mobility Anchoring, let’s delve into the mechanics of how it actually operates. Understanding these processes is crucial for network administrators looking to implement and optimize their wireless networks.

Roaming Scenarios

Mobility anchoring comes into play in various roaming scenarios. Here are the most common ones:

  1. Intra-controller roaming
  2. Inter-controller roaming
  3. Inter-subnet roaming
Roaming TypeDescriptionMobility Anchoring Role
Intra-controllerClient moves between APs on the same controllerMinimal – handles local switching
Inter-controllerClient moves between APs on different controllersMaintains client’s original IP and session
Inter-subnetClient moves between different IP subnetsTunnels traffic back to anchor controller

Anchor Controller vs. Foreign Controller

In mobility anchoring, two key players emerge:

  1. Anchor Controller: The original controller where the client first associates
  2. Foreign Controller: Any subsequent controller the client connects to while roaming

The anchor controller maintains the client’s IP address and session information, while the foreign controller facilitates communication between the client and the anchor.

Data Path and Control Path

Mobility anchoring utilizes two distinct paths:

  • Control Path: Handles signaling between controllers for client information and roaming events
  • Data Path: Manages the actual flow of client traffic

When a client roams, the control path updates client information across controllers, while the data path ensures seamless connectivity by tunneling traffic when necessary.

Client Association Process

The client association process in mobility anchoring involves several steps:

  1. Client associates with an access point
  2. Controller determines if it’s the anchor or foreign controller
  3. If foreign, it communicates with the anchor controller
  4. Anchor controller maintains the client’s IP and session
  5. Data traffic is tunneled if needed to maintain connectivity

This process ensures that clients maintain their original IP addresses and sessions, even as they move between different parts of the network.

As we move forward, we’ll explore the practical implementation of mobility anchoring and its various applications in real-world scenarios.
