It keeps + * a two lists of static routes: one containing interface routes and one + * holding the remaining ones. Interface routes are inserted and removed according + * to interface events received from the core via the if_notify() hook, routes + * pointing to a neighboring router use a sticky node in the neighbor cache + * to be notified about gaining or losing the neighbor and finally special + * routes like black holes or rejects are inserted all the time. + * + * The only other thing worth mentioning is that when asked for reconfiguration, + * Static not only compares the two configurations, but it also calculates + * difference between the lists of static routes mentioned in the old config + * and the lists in the new one and it just inserts the newly added routes + * and removes the obsolete ones. + */ + #undef LOCAL_DEBUG #include "nest/bird.h" |
