RIP Interview Questions & Answers
1) How does RIP differ from EIGRP?
A: 1) RIP is classful routing protocol whereas EIGRP is
classless routing protocol.
2) RIP has a maximum hop count of 15 whereas EIGRP maximum hop count 255.
3) RIP uses
periodic updates, EIGRP uses Incremental/Triggered updates.
4) RIP uses
Bellman-Ford algorithm, EIGRP uses the DUAL algorithm.
5) RIP has An administrative distance of 120, EIGRP has 90.
6) Convergence
is slower in RIP, whereas it is faster in EIGRP.
2) What is Split Horizon in RIP?
A: Split Horizon is a loop prevention mechanism in RIP which
prevents advertising of update or route on the same interface from which it is
received the update message.
3) What is Route Poisoning?
A: Route Poisoning is a loop prevention mechanism in RIP
which advertises unknown destination with a hop count of 16 or destination unreachable
4) What is the difference between RIP and RIPng?
A:
1) RIPng supports IPV6 whereas RIP does not.
1) RIPng supports IPV6 whereas RIP does not.
2) RIPng
supports IPV6 AH/ESP authentication whereas RIP has its own specific
authentication methods.
3) RIPng allows to
run multiple RIP processes on a single router, RIP does not support this feature.
4) RIPng uses port number UDP 521, RIP uses port number UDP 520.
4) RIPng uses port number UDP 521, RIP uses port number UDP 520.
5) What is the purpose of the Passive Interface?
A: Passive Interface feature used in routing protocol to
stop sending hello and update messages on a particular interface.
