5 - An adjacency represents how to send different traffic types to a peer
6 - The principles properties of an adjacency are the interface and rewrite.
7 The rewrite will be prepended to the packet as it is forward through the
9 - The rewrite is provided either by the interface type. It can be constructed
10 either from fixed interface properties (i.e. src,dst IP address on a P2P
11 tunnel) or from a resolution protocol (like ARP on an Ethernet link).
12 - An Adjacency is said to be complete when the rewrite is present and
13 incomplete when it is not,
14 - An adjacency that is a leaf in the DPO graph is terminal/normal (i.e on
15 a physical interface). When not terminal it is termed a midchain (i.e.
16 one on a virtual interface, e.g. GRE tunnel). Midchain adjacencies can be
17 stacked/joined onto the the DPO graph that described subsequent forwarding
18 (i.e. how to send the the GRE tunnel's destination address).
19 - Glean adjacencies describe how to broadcast packets onto a subnet
21 description: "Adjacencies represent the next-hop information required to reach a directly connected neighbour."
