Ans:- OSPF is the first Open Standard Link State Routing Protocol. It's a Classless Routing Protocol meaning when updates are sent they send both IP address and Subnet mask.
Administrative Distance is 110.
Metric used is Cost i.e. Cost= 108
Q2:- What is SLIP (Serial Line Internet Protocol)?

Q1:-What is BGP (Border Gateway Protocol)?

Ans:- An authentication mechanism used to verify user or host identity. Kerberos uses encryption to prevent intruders from discovering passwords and gaining unauthorized access to files.

Q1:- What is EGP (Exterior Gateway Protocol)?
Ans:-
It is the protocol the routers in neighboring autonomous systems use to identify the set of networks that can be reached within or via each autonomous system.
Q2:- What is Autonomous System?

Ans:-A group of Networks under mutual administration that share the same routing methodology. Autonomous Systems are subdivided by Areas and must be assigned an individual 16-bit number by the IANA.
