Which are two types
of routing protocol
IGP or interior gateway protocol
EGP or exterior gateway protocol
Why we use IGP
protocol
To exchange routing updates within same AS
What are the examples
of IGP protocols
OSPF, RIP, EIGRP
What is EGP protocol
Used to exchange routing information between routers
belonging to different autonomous system
Which is the EGP
protocol
BGP
What is the main goal
of BGP
To provide interdomain routing
Loop free exchange of routing information between autonomous
system
What is an Autonomous System or AS
Set of routers under common administration
How can we exchange routing information within same AS
Using IGP protocols
Suppose we have two router r1 and r2. Both belong to
different AS. R1 belong to AS 100 and R2
belong to AS 200. How can we exchange routing information between these
two routers
Using BGP protocol
Which transport protocol and port number used by BGP
TCP as the transport protocol and port 179
We have following network
Which routing protocol can be run inside As 100, AS 200, AS
300 AS 400
We can run IGP protocol such OSPF, EIGRP, RIP inside AS
autonomous system
Which routing protocol can we run between R1 and R6
BGP
We have ISP network
ISP network contain following client ABC university PQR
university and XYZ enterprise
Which routing protocol can we run within ABC university or
PQR university or XYZ enterprise
We can run IGP protocol within same domain or autonomous
system
We can run EIGRP, OSPF or RIP
In the above ISP network ABC university and PQR university
wants to have some form of communication. How can we achieve communication
between two different universities
Using BGP
How can we achieve connectivity between two different ISP
Using BGP protocol
