Bonds

Bonds are the central object in SD-WAN. A bond refers to a
collection of legs, connected IPs, CPE NAT IPs, routes, and other
settings.

The configuration for a single bond is used at two locations:

#. At the CPE. For example, the CPE uses the bond configuration to
   configure its Ethernet interfaces based on the legs and connected IPs
   in the bond.
#. At the aggregator. For example, the aggregator uses the bond
   configuration to set up the correct routes for the connected IPs, CPE
   NAT IPs, and routes.

A bond is closely associated with a `bonder <bonders.html>`__ (the hardware that runs the
bond at the customer's premise), but can easily be moved from one aggregator to
another using the appropriate forms on the management server.
