In this case, the longest prefix of the candidate routes is 192.168.20.16/28, since its subnet mask (/28) is longer than the other entry's mask (/16), making the route more specific. Forwarding tables often contain a default route , which has the shortest possible prefix match, to fall back on in case matches with all other entries fail.
IP forwarding algorithms in most routing software determine a route through a shortest path algorithm. In routers, packets arriving at an interface are examined for source and destination addressing and queued to the appropriate outgoing interface according to their destination address and a set of rules and performance metrics.
The specific characteristics of routing protocols include the manner in which they avoid routing loops, the manner in which they select preferred routes, using information about hop costs, the time they require to reach routing convergence, their scalability, and other factors such as relay multiplexing and cloud access framework parameters.
In the context of network routing, route filtering is the process by which certain routes are not considered for inclusion in the local route database, or not advertised to one's neighbours. Route filtering is particularly important for the Border Gateway Protocol on the global Internet , where it is used for a variety of reasons.
C This is a QUIC library that's crypto library agnostic and works with OpenSSL or GnuTLS. For HTTP/3, it needs a separate library like nghttp3.

The letter "S" indicates that the route is a static route that has, for all intents and purposes, been added manually to the router process by the administrator and installed into the routing table.

Static routes, connected routes, and routes from dynamic configuration protocols can be redistributed by dynamic routing protocols. For instance, a router may have a static or connected route for a local network segment, which is then redistributed over dynamic routing protocols to enable connectivity to that network.
In networking and in graph theory, capillary routing, for a given network, is a multi-path solution between a pair of source and destination nodes.Unlike shortest-path routing or max-flow routing, for any given network topology - only one capillary routing solution exists.
