* DOC: Pipe
|
||||
*
|
||||
* The Pipe protocol is very simple. It just connects to two routing tables
|
||||
* using proto_add_announce_hook() and whenever it receives a rt_notify()
|
||||
* about a change in one of the tables, it converts it to a rte_update()
|
||||
* in the other one.
|
||||
*
|
||||
* To avoid pipe loops, Pipe keeps a `being updated' flag in each routing
|
||||
* table.

/**
|
||||
* DOC: Static
|
||||
*
|
||||
* The Static protocol is implemented in a very straightforward way. 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.
