Routing Protocols - Definitions

Question 1

IGP

Answer 1

It’s a routing protocol that we would use to route between networks that are on our internal autonomous system.

Question 2

OSPF

Answer 2

-Internal
- find shortest path between internal gateway

Question 3

RIPv1

Answer 3

is a distance-vector interior gateway routing protocol used to distribute routing information within a small or medium-sized network.

Question 4

RIPv2

Answer 4

support for Variable Length Subnet Masks (VLSM), which allows for more efficient use of IP address space, and the inclusion of authentication mechanisms for securing routing updates.

Question 5

IS-IS

Answer 5

is a link-state interior gateway routing protocol used to distribute IP routing information throughout a network of routers within an autonomous system (

Question 6

EIGRP

Answer 6

advanced distance-vector routing protocol used to dynamically route data within a network. Faster convergence and greater scalability compared to protocols like RIP. Supports IPv4&6, route summarization, load balancing, and support for VLSM.

Question 7

BGP

Answer 7

THE ONLY EXTERNAL ONE! Path Vector (system hops, not router hops)

Question 8

MTU

Answer 8

largest size of a data packet that can be transmitted over a network protocol without fragmentation.

Question 9

FHRP

Answer 9

allowing multiple routers to act as a single virtual gateway, providing redundancy and ensuring uninterrupted connectivity in case of a router failure.
- HSRP (cisco)
-VRRP
-GLBP (Cisco)

Question 10

GRE

Answer 10

describes it as a tunneling protocol used in computer networks to encapsulate packets from one network protocol within packets from a different network protocol.
-each friend has their own secret tunnel

Question 11

mGRE

Answer 11

refers to a variant of the Generic Routing Encapsulation (GRE) tunneling protocol that allows multiple endpoints to communicate with each other over a single GRE tunnel.
-everyone shares the same tunnel
