Most people don't realize that KERNEL does not run *ANY* routing
algorithms for IP (aside of table scans). Programs running in
user-space do feed the kernel route tables whatever they wish,
which ever way they create it. Then kernel uses those (from its
point of view: "given") tables to do IP packet forwarding.
The repertoire of those available algorithms/protocols for the
route dataset discovery is -- considerable. Simple things
like Distance Vector (RIP), more complicated Link State things
(OSPF), all the way to policy controlled Autonomous System
traversal decissions (e.g. BGP). (Plus Distance Vector
Multicast Reverse Path (protocol), plus Protocol Independent
Multicasting protocol, plus...)
Programs implementing them, that is time for a FAQ...
