13.3 Cross Gateway Roaming

Configuration path: Main Menu >> Network >> Client Mobility
Cross Gateway roaming feature enables an end user to seamlessly move
around large network deployment where there are multiple Controllers in
service. Normally when a user moves from edge AP to another edge AP that
is managed by another Controller, the user would experience network
disconnection and would require re-login procedure in order to continue
surfing the net.
With Cross Gateway roaming enabled, the end user would not experience
network interruption. The traffic would be tunneled back to the original
Controller for forwarding into the internet.
Cross Gateway roaming architecture design adopted is a star topology design
where one Master Node may have up to 15 Slave Node peers. The term
master Node simply means that this node takes its place in the center of the
star topology.
The role determination is completely dependent on the administrator settings.
To establish roaming partnership, configure a Controller to be Master Node,
and another Controller to be Slave Node. Make sure that the Secret Key and
both Controller's WAN interface are routable.
Configure Slave Node's IP address and secret key.
