Enum SourceSelection 

pub enum SourceSelection {
    EgressPort,
    Port(PortId),
}

Which of the router’s addresses a request it originates names as its source.

Variants

EgressPort

The router’s address on the port the request leaves by: no SNET or SADR, so the next router adds that port’s network and the router’s MAC there, as it does for any node on that network (Clause 6.5.4). A global broadcast leaves by every port, so each copy is from that port’s address. The default.

In a site with a loop of routers, each port’s bare copy is a different origin to the routers that relay it, so another router may deliver this router’s global broadcast to its own application once per port, duplicate suppression or not (Options::duplicates keys by origin). Use SourceSelection::Port there: every copy then names one origin.

Port(PortId)

The router’s address on this port’s network: SNET and SADR naming it, whichever port the request leaves by, or none when it leaves by this port, where the link source already says so. A global broadcast leaves by every port: with SNET and SADR on the others, and without them on this one. For an application that answers to one address.
