Best Answer

Routing protocol is used to dynamically learn routing information so routers know where to send packets. The only other option is to manually define all routers within a network which would be very impractical.

Which protocol offers guaranteed delivery and is connection oriented?

Transmission Control Protocol (TCP) is used when data reliability is needed since it is connection oriented and guarantees delivery.


What is Difference between static and dynamic routing tables?

Technically, there is no such thing. The routing table has several entries (think of them as lines); the individual LINES in the routing table can be static or dynamic; and the routing table in its entirety can have both types. A static entry is programmed (hard-coded) by a network administrator. A dynamic entry is one which the router learns from a routing protocol, such as RIP, EIGRP, OSPF, BGP, etc. The routers "talk" to one another, and tell one another that they have routes to certain networks; the router that receives such updates will update its routing table as a result. Such entries are temporary, and expire after a relatively short time.


What the difference between protocol stack and protocol suite?

- In your own words, define the term 'protocol' and what is the difference between protocol and protocol suite


What is difference between serial interface and Ethernet interface?

The FastEthernet interface of R1 is disabled. One of the default routes is configured incorrectly. A routing protocol is not configured on both routers. The default gateway has not been configured on both routers.


Knowing the difference between the nipr and sipr helps prevent?

It helps prevent people from gaining access to information they're not cleared to access. The Secret Internet Protocol Routing Network (SIPRNET) contains classified information. Wires for the SIPRNET are marked so don't even think about touching them, let alone accessing the network, without proper clearance. The Non-classified Internet Protocol Routing Network (NIPRNET) is roughly equivalent to your home network in terms of security; only non-classified information should exist on the network.

What are routing protocols Why do you need them Name a few?

A routing protocol is a formula that specifies how routers are communicating to each others. Types of routing protocols include Interior Gateway Protocol, Distance vector protocol and Classful or classless protocol. Routing protocols are required to determine the appropriate paths for data transmission.


What is flat routing protocol?

Flat routing protocol is a network communication protocol implemented by routers in which all routers are each other's peers. Flat routing protocol distributes routing information to routers that are connected to each other without any organization or segmentation structure between them. Flat routing protocols are primarily those that don't work under a predefined network layout and perimeter. They enable the delivery of packets among routers through any available path without considering network hierarchy, distribution and composition. Flat routing protocol is implemented in flat networks where each router node routinely collects and distributes routing information with its neighboring routers. The entire participating node addressed by flat routing protocol performs an equal role in the overall routing mechanism. Routing Information Protocol, Interior Gateway Routing Protocol and Enhanced Interior Gateway Routing Protocol are popular examples of flat routing protocols.
