What type routing protocol is RIP?
Distance Vector
What type of routing protocol is IGRP?
Distance Vector
What type of routing protocol is OSPF?
Link State
What type of routing protocol is IS-IS?
Link State
What type of routing protocol is EIGRP?
Hybrid
What type of routing protocol sends its entire routing protocol at specific intervals?
Distance Vector
In their simplicity, distance vector protocols have ___________ issues.
Looping
What are the five distance vector loop prevention mechanisms?
Maximum distances, route poisoning, triggered updates, split horizon, hold down timers.
What is the maximum distance for RIP?
16 hops
What does route poisoning do?
It sets the maximum distance to 16, making the route dead.
What is split horizon?
Tells routers to not send updates back in the same direction that they received them on networks that are being advertised.
What does a hold timer do?
Routing updates are ignored for a certain amount of time.
What is a flapping interface?
An interface that continuously goes up and down extremely fast.
How do link state protocols exchange routes?
They form neighbor relationships instead of sending out broadcasts.
What happens after routing tables are exchanged with a link state routing protocol?
The routers send small, event-based updates.
What are the two link state protocols?
OSPF, IS-IS
