No point to ROUTE_REJECTION #7

Open martinthomson opened 3 years ago

martinthomson commented 3 years ago

I'm assuming that servers are the only ones that will ever really advertise routes. (They should probably advertise ::/0 by default even.) Why would a client reject a route as opposed to just not using it?

DavidSchinazi commented 3 years ago

ROUTE_REJECTION isn't a response to ROUTE_ADVERTISEMENT, they both go in the same direction. For example the server could say:

ROUTE_ADVERTISEMENT 0.0.0.0/0
ROUTE_REJECTION 10.0.0.0/8

to indicate that it's willing to route everything (v4-wise) except for 10/8

Another possible name for ROUTE_REJECTION is ROUTE_WITHDRAW, but that has implications we didn't quite like, so we went with REJECTION for the initial draft.

Ah, that's not particularly clear. Maybe ROUTE_INCLUSION and ROUTE_EXCLUSION then.
