Routing Protocols Flashcards
What is the acronym RIP
Routing Information Protocol
What is the acronym IGRP
Interior Gateway Routing Protocol
What is the acronym GRE
Generic Routing Encapsulation
What does RIP do?
It is a dynamic routing protocol that uses hop count as a routing metric to find the best path between the source and the destination network
What does IGRP do?
it is a proprietary distance vector routing protocol used to communicate routing information within a host network. It was invented by Cisco.
What does GRE do?
it is one example of a basic, nonsecure, site-to-site VPN tunnelling protocol. It was invented by Cisco
What is hop count?
is the number of routers occurring in between the source and destination network.
What is the best route regarding hop count?
the one with the least hops
What is the maximum hop count for RIP
15 hops. 16 is considered unreachable
What has RIP been replaced by?
OSPF, IGRP
How does IGRP route traffic?
The protocol ensures that every router has routing tables updated with the best available path.
How many hops can IGRP do?
maximum hop count of 255
What is the benefit of IGRP?
It is continuously updating the routing tables and route
What is a benefit of GRE over other tunnelling solutions
It can do multicast traffic
