Routes Flashcards
What are the ways a router knows where to forward traffic?
Statically Configured
Dynamically Configured
What is the default route?
0.0.0.0 /0
Used when no networks are found in routing table
You assign a device to a default route to handle the packet
What is the routing table?
A list of networks that a router uses to forward packets
Directly connected
Statically configured
Dynamically learned
What is a Dynamic Routing Protocol?
Routers share information about networks and reachability to other routers (IGP/EGP)
What is IGP?
Interior Gateway Protocol
What are the types of IGP?
OSPF, IS-IS - Link State
EIGRP, RIPv2 - Distance Vector
What is OSPF?
Open Shortest Path First
Cost metric
What is EIGRP?
Enhanced Interior Gateway Protocol
Distance vector + Link-State hybrid
What is RIP?
Routing Information Protocol
Lowest hop count
What is Link State vs Distance Vector?
Link State (faster convergence) is a broadcast announcement of a particular network Distance Vector (less reliable) is a statement of a reachable network
What is convergence?
The state of all routers having the same topology about the network in which they operate
What is EGP?
Exterior Gateway Protocol
What are the types of EGP?
BGP
What is BGP?
Boarder Gateway Protocol
What is IGRP?
Interior Gateway Protocol
MTU, Latency, Bandwidth
