+name: Adjacency
+maintainer: Neale Ranns <nranns@cisco.com>
+features:
+ - An adjacency represents how to send different traffic types to a peer
+ - The principles properties of an adjacency are the interface and rewrite.
+ The rewrite will be prepended to the packet as it is forward through the
+ interface.
+ - The rewrite is provided either by the interface type. It can be constructed
+ either from fixed interface properties (i.e. src,dst IP address on a P2P
+ tunnel) or from a resolution protocol (like ARP on an Ethernet link).
+ - An Adjacency is said to be complete when the rewrite is present and
+ incomplete when it is not,
+ - An adjacency that is a leaf in the DPO graph is terminal/normal (i.e on
+ a physical interface). When not terminal it is termed a midchain (i.e.
+ one on a virtual interface, e.g. GRE tunnel). Midchain adjacencies can be
+ stacked/joined onto the the DPO graph that described subsequent forwarding
+ (i.e. how to send the the GRE tunnel's destination address).
+ - Glean adjacencies describe how to broadcast packets onto a subnet
