Topology

"Tenant"→"Config"→"Network Service"→"Topology"

The topology of each VRF needs to be configured separately.

Topologies are divided into two types: single-layer and hierarchical:

Single-layer topology: Backbone mode, hub-spoke mode, hybrid mode.
Hierarchical topology: Consisting of multiple regional topologies. Each region is a backbone mode network, optionally with gateway links. Hubs of each region form another layer of backbone or hub-spoke network.

Corresponding transport must be enabled on WAN interfaces in the site configuration, otherwise tunnels won't be established!

Single-Layer Topology

Select one mode in: backbone, hub-spoke or hybrid.

In backbone mode site can connect to one or more gateways, with priorities assigned in order.

In hub-spoke mode, select hubs and configure priorities. Other sites are spokes.

In hub-spoke mode, hubs and at least one side of full-mesh link must have tunnel endpoint address configured on WAN interface, for the tunnel to be established.
