The document discusses interledger routing and connector relationships. It covers the connector-to-connector routing protocol, how routing advertisements and withdrawals are used to update routing logs, and how connector configurations can specify plugin types and relationship types like peer, customer, or provider to determine routing preferences. An example routing topology is presented to tie these concepts together.

- 8. WKEGKJJD6ITW3SPXJHE PMKFEX6ANMB7U 8 Routing Terminology Routes are an advertisement by a connector, stating they can reach a destination. Prefixes are ILP address prefixes covering a portion of the address space. The Origin of a route is the connector who first advertised the route. A Routing Table is a lookup table of routes, indexed by prefix.
