An EoIP tunnel is created between the client and the anchor controller to provide seamless connectively as the client is associated with the new AP.

The client entry on the original controller is passed to the database on the new controller.

The new controller assign an IP address from the new subnet to the client.

The client database on the original controller is updated with the anchor entry, and the new controller database is updated with the foreign entry.

Data forwarding is stopped until the routing protocols reconverge after the switchover.

The standby route processor initialization is started when the primary router processor fails.

The standby route processor is fully initialed and state information is maintained.

User sessions are immediately recreated on the new active route processor.

Data forwarding can continue along known paths until routing protocol information is restored.

A new security context is applied for each controller to which the client is associated, but the IP address remains the same.

The client must be associated to a new controller where a new IP address and security context are applied.

The client retains the same IP address and security context.

The client is marked as foreign in the database of each new controller to which it is connected.

Devices are assigned to virtual networks based on their VLAN membership.

Scalable group tags are used for macrosegmentatlon.

Virtual networks are used for microsegmentation.

All traffic is Layer 3 within the fabric.

It facilitates software upgrades to network devices from a central point.

It facilitates a vulnerability assessment of the network devices.

It uses a predefined configuration through parameterized elements or variables.

It provides a high-level overview of the health of every network device.

Clients must obtain a new IP address when they roam between APs.

It provides seamless roaming between APs that are connected to different Layer 3 networks and different mobility groups.

It is only supported on controllers that run SSO.

It provides seamless client roaming between APs in different Layer 3 networks but within the same mobility group.
