Difference Between Static Route and Dynamic Route

Static Routing	Dynamic Routing
Does not use routing protocol	Use routing protocol
It is ideal for small/simple networks	It is suitable for large/complex networks
Configuring static route involve less cost	Dynamic routing involves cost in terms of CPU processes and bandwidth on the network links
It is maintained by Network Administrator	Routers are responsible for maintaining paths
Routes cannot be changed until authorized by the administrator	Routing protocols find the routes for traversing the packets
Routers are not updated dynamically in the routing table and hence cannot detect inactive routes	Routing protocols update the routing table with the update routes
Link failure disturb rerouting	Link failure does not disturb the rerouting
Link failure affects the network	Link failure does not  affect the network
Better Security	Less Security
Configuration is difficult	Configuration is easy
Basic network knowledge is required	Advanced network knowledge needed

When an interface of a router is activated, what is happened? 

The router does the following:

• -> Read the IP configuration of the interface.
• -> Extract network information from the IP configuration.
• -> Find the extracted network information in the routing table.
• -> If the routing table already contains an entry for the extracted network, the router updates that entry.
• -> If the routing table contains no entry for the extracted network, the router adds an entry for the extracted network.

The following image shows how the router0 learns the network address from the IP configuration of the FastEthernet 0/0 interface and adds that network address in the routing table.

Metric of Various Routing Protocol

By the way, What is Metric?

Metric is the criteria of finding best path selection

Administrative Distance

What is this?

Administrative distance is the first criterion that a router uses to determine which routing protocol to use if two protocols provide route information for the same destination.

Most Important 

                

Protocol	Administrative Distance
Connected	0
Static	1
EIGRP	90
OSPF	110
RIP	120

If PC-A want to reach to server , which protocol will use?

EIGRP protocol will be used, because EIGRP matric value is 90 which is less than OSPF metric value(120)

Difference Between RIPv1  and  RIPv2

    

                                                

SL.	RIPv1	RIPv2
1.	RIPv1 is a Distance-Vector Routing protocol.	RIPv2 is also Distance-Vector Routing Protocol.
2.	It can supports class full network only.	It can support class full and classless networks.
3.	It does not support for authentications.	It supports for authentications.
4.	It hop count limit is 15.	It hop count limit is 15.
5.	It does not support for VLSM and discontinuous networks.	It supports for VLSM and discontinuous networks.
6.	It is less secure.	It is more secure.
7.	RIPv1 use Broadcast traffic for updates.	RIPv2 use Multicast traffic for updates.
8.	RIPV1 does not provide trigger updates.	RIPv2 provides trigger updates.
9.	RIPV1 not send subnet mask to routing table.	RIPv2 send subnet mask to routing table.
10.	RIPv1 do not support manual route summarization.	RIPv2 support manual route summarization.
