Q6. What is OSPF and how it is differ from EIGRP ?
Ans. 
OSPF is a link-state routing protocol while EIGRP is a distance-vector routing protocol.
• OSPF uses Dijkstra algorithm to calculate the shortest path while EIGRP uses Diffusing Update Algorithm (DUAL)

• OSPF supports VLSM and CIDR while EIGRP does not

• OSPF is an open standard protocol while EIGRP is Cisco proprietary

• OSPF has a lower administrative distance (110) compared to EIGRP (90)
