Struct RouteEntry 

pub struct RouteEntry {
    pub port_index: usize,
    pub directly_connected: bool,
    pub next_hop_mac: MacAddr,
    pub last_seen: Option<Instant>,
    pub last_used: Option<Instant>,
    pub reachability: ReachabilityStatus,
    pub busy_until: Option<Instant>,
    pub flap_count: u8,
    pub last_port_change: Option<Instant>,
}

A route entry in the router table.

Freshness is split (RB-06): last_seen is control-plane confirmation (learning claims and management applies only), while last_used is data-plane forwarding use. Expiry keys off last_seen only so sustained traffic cannot manufacture fresh route evidence. Busy/Available marks touch neither timestamp.

Fields

port_index: usize

Index of the port this network is reachable through.

directly_connected: bool

Whether this is a directly-connected network (vs learned via another router).

next_hop_mac: MacAddr

MAC address of the next-hop router (empty for directly-connected networks).

last_seen: Option<Instant>

When this learned route was last confirmed. None for direct routes.

last_used: Option<Instant>

When this route was last used for forwarding. None until first use or after a port change installs an unused path. Never extends expiry.

reachability: ReachabilityStatus

Recorded reachability state of this route.

busy_until: Option<Instant>

Deadline after which a Busy status auto-clears (spec 6.6.3.6).

flap_count: u8

Number of times this route changed ports within the flap detection window.

last_port_change: Option<Instant>

When the route last changed ports.
