Daisy chaining

When stitching services between the cellular interface and the WLAN interface, it is possible to create a daisy chain topology; see Daisy chain topology for stitched services.

Figure 1. Daisy chain topology for stitched services

In a daisy chain topology, a hub node is configured as described in section Stitching services between the cellular interface and a WLAN AP and a chain node is introduced to further extend the WLAN network by creating multiple hops between the hub node and the last node in the chain. The OSPF control plane is configured on all WLAN interfaces and BGP is configured from the hub node to the last node in the chain. If services terminate on the chain node, a BGP session is configured between the chain node and the hub node.
