Tunnels in an Overlay
OverlayThe complete set of logical connections, making use of tunnels and physical connections in the underlay network between Silver Peak appliances. These are associated with a particular Business Intent Overlay (BIO). Each set of overlay connections between sites in a particular BIO might make use of multiple underlay connections. An overlay might make use of some or all of the physical networks, and tunnels, with differing overlays using different tunnels for different data types. tunnelsEncapsulating one type of network protocol (called the payload protocol) within a different delivery protocol. A logical connection between two devices, in our case, two Silver Peak appliances. consist of bonded underlayThe physical transport network and its site-to-site connections, including MPLS networks, the Internet, LTE networks, or private lines. It also includes the tunnels built between Silver Peak appliances across any physical networks. tunnels. Tunnels are created automatically, and you don't need to manually configure them. BIOs use the Labels created in Deployment Profiles to define how traffic is routed and optimized between sites.
