Gateway protocols are used to update routing tables.
Interior Gateway Protocols
Autonamous systems that self-update routing tables.
Link State Protocols
link state protocols store information about every router on the network.
this takes much more memory, but updates very quickly.
OSPF IS-IS Distance Vector Protocols
Measures how many hops each known network is away from self.
Then sends this list to every neighboring router.
Since routers are only updated from direct neighbors, routes with many hops propagate very slowly.
Exterior Gateway Protocols
Communication between multiple Interior Gateway Protocol-driven autonomous systems.
border gateway protocol
