Routing

Question 1

Default Static Route

Answer 1

IPv4- 0.0.0.0/0
IPv6- : :/0

Question 2

Routing Information Protocol (RIP)

Answer 2

Distance Vector Protocol
Interior
Uses hop count
Oldest, uses UDP

Question 3

Open Shortest Path First (OSPF)

Answer 3

Link State Protocol
Interior
Uses cost
Very popular

Question 4

Intermediate System to Intermediate System (IS-IS)

Answer 4

Link State Protocol
Interior
Uses cost
Not as popular

Question 5

Enhanced Interior Gateway Routing Protocol (EIGRP)

Answer 5

Hybrid (Distance Vector & Link State) Protocol
Interior
Uses bandwidth & delay (hops)
Cisco-only networks

Question 6

Border Gateway Protocol (BGP)

Answer 6

Path Vector Protocol
Exterior
Uses autonomous system hops, instead of router hops
Widespread utilization, backbone of internet, slow convergence

Question 7

First Hop Redundancy Protocol (FHRP)

Answer 7

Provides automatic failover to a backup router

Question 8

Hot Standby Router Protocol (HSRP)

Answer 8

Cisco redundancy protocol, 2 or more routers present as a single virtual router to establish a fault-tolerant Default Gateway

Question 9

Virtual Router Redundancy Protocol (VRRP)

Answer 9

Standard redundancy protocol, similar to HSRP
Open standard, multiple routers configured
Simple automatic election scheme

Question 10

Gateway Load Balancing Protocol (GLBP)

Answer 10

Cisco developed, adds load balancing
Multiple routers can forward packets, distribute traffic
