What is the difference between EIGRP and OSPF?

What is the difference between EIGRP and OSPF?


EIGRP
---------
It Is a Cisco standard routing protocol Now open standard protocol from 2013
It supports Maximum 255 Routers in The Network.
EIGRP is denoted by D for internal and D-ex for external in Routing Table
EIGRP is the only protocol that have backup path to reach at destination if multiple path are present.
EIGRP is the only one router in the world that support multiple routed protocols.
It Is Basically Use For Medium to Lager Size Organization in the network.
It’s Administrative distance Is 90 for internal and 170 for external.
EIGRP Routing protocol We Can Create a separate administrative boundary in the Network through different as we need to redistribute those network.
It calculates the Metric In Terms Of Bandwidth And delay.
EIGRP Works on DUAL(Diffusing Update Algorithm) Algorithm
EIGRP Supports VLSM
EIGRP Creates three table In the Router
>>>Neighbor Table
>>>Topology Table
>>>Routing Table
Its use RTP(Reliable transport protocol) for acknowledgement of EIGRP packet. use own protocol no 88.
Its Network Layer protocol
Hello Time-5 Sec(BMA and P2P network) 60 Sec(NBMA)
Dead time-15 Sec(BMA and P2P network) 180 Sec(NBMA)
EIGRP send Copy of Its Routing Table to directly connected neighbors at time of neighbor adjacency EIGRP use multicast address 224.0.0.10
---------------------------------------------------------------------------------
OSPF
--------
It Is A Industry standard Routing protocol
It supports Unlimited router in the Network
It Is Denoted By O for intra O-IA for inter OSPF and OE2 for External in routing Table 
It Is a More Intelligent routing protocol
It Is basically Use For Larger Size Organization in The Network
It’s Administrative distance is 110
In OSPF Routing protocol We Can Create a separate administrative boundary in the Network through Area No. within The same area all of The routers Area exchanging The Route information From Neighbor router in the network.
It Calculates the Metric in terms of Bandwidth
OSPF works on DIJKSTRA Algorithm
OSPF Supports VLSM OSPF Routing Creates three Table in the router—
>>>Neighbor Table
>>>Database Table
>>>Routing Table
Its not use any protocol like TCP or UDP its directly use data encapsulation to IP address port no 89.
Its Network Layer protocol
Hello Time-10 Sec(BMA And P2P) 30 Sec (NBMA)
Dead time-40 Sec(BMA And P2P) 120 Sec(NBMA)
OSPF send Topology table at the time of neighbor adjacency
OSPF use multicast address 224.0.0.5 neighbor adjacency and 224.0.0.6 for DR and BDR
