Is Rip still used?
RIP, like all routing protocols, is designed to disseminate network information pertinent to routers.
At the most basic level, routers need to know what networks are reachable and how far away they are.
RIP does this, and it’s still widely used today..
What is CIDR in subnetting?
Classless inter-domain routing (CIDR) is a set of Internet protocol (IP) standards that is used to create unique identifiers for networks and individual devices. … The most important of these groups is the network address, and it is used to identify a network or a sub-network (subnet).
What does 24 mean in IP address?
This is called “slash notation”. There is a total of 32 bits in IPv4 address space. For example, if a network has the address “192.0. 2.0/24”, the number “24” refers to how many bits are contained in the network. From this, the number of bits left for address space can be calculated.
What is the administrative distance of OSPF?
By default, OSPF has a default administrative distance of 110 and RIP has a default administrative distance of 120.
What is classless and Classful?
Classless addressing and classful addressing refer to two different ways to think about IP addresses. … Both terms refer to a perspective on the structure of a subnetted IP address. Classless addressing uses a two-part view of IP addresses, and classful addressing has a three-part view.
What is difference between classful and classless routing?
In classful routing, hello messages are not used. While in classless routing, hello messages are used. … In classful routing, address is divided into three parts which are: Network, Subnet and Host. While in classless routing, address is divided into two parts which are: Subnet and Host.
What is Classful subnetting?
Classful subnetting is a method of splitting a classful network number into two or more smaller subnets. The subnets will all be the same size, determined by the maximum number of hosts per subnet. A single custom subnet mask is used to configure the subnets.
Why BGP is used over OSPF?
With BGP on the other hand, the size of the routing table dictates the required device resources. Scale: BGP is more flexible and scalable than OSPF and it is also used on a larger network. Preferred path: OSPF is used to determine the fastest route while BGP puts emphasis on determining the best path.
What does Classful mean?
A classful network is a network addressing architecture used in the Internet from 1981 until the introduction of Classless Inter-Domain Routing in 1993. The method divides the IP address space for Internet Protocol version 4 (IPv4) into five address classes based on the leading four address bits.
What is subnetting and Supernetting?
Subnetting is the procedure to divide the network into sub-networks or small networks. Supernetting: Supernetting is the procedure to combine the small networks into larger space. … Subnetting is implemented via Variable-length subnet masking, While supernetting is implemented via Classless interdomain routing.
Which one is the hybrid protocol?
An example of a hybrid routing protocol is the Enhanced Interior Gateway Routing Protocol (EIGRP), developed by Cisco.
Which is better RIP or OSPF?
Unlike RIP protocol that has only 15 hops at most, OSPF has no limitations in hop count. So OSPF converges faster than RIP, and has better load balancing. The drawbacks of OSPF, however, is that it doesn’t scale when there are more routers added to the network.
What are the benefits of classless addressing?
Advantages of classless addressing over classful addressing: Efficient address-space allocation is available in classless addressing. Memory is allocated in terms of bits and bytes rather than huge chunks of contiguous memory. It eliminates any class imbalances. Routing entries are much more efficient.
What is considered a classless routing protocol?
The classless IPv4 routing protocols (RIPv2, EIGRP, OSPF, and IS-IS) all include the subnet mask information with the network address in routing updates. Classless routing protocols support VLSM and CIDR. IPv6 routing protocols are classless.
What is classless address?
Classless Addressing is an improved IP Addressing system. It makes the allocation of IP Addresses more efficient. It replaces the older classful addressing system based on classes. It is also known as Classless Inter Domain Routing (CIDR).
Does OSPF use hop count?
Like EIGRP, OSPF bases its metric by default on link bandwidth, so that OSPF makes a better choice than simply relying on the router hop-count metric used by RIP. But OSPF uses much different internal logic, being a link-state routing protocol rather than a distance vector protocol.
What are the 3 major classes of an IP network?
Currently there are three classes of TCP/IP networks. Each class uses the 32-bit IP address space differently, providing more or fewer bits for the network part of the address. These classes are class A, class B, and class C.
What is OSPF protocol in networking?
The OSPF (Open Shortest Path First) protocol is one of a family of IP Routing protocols, and is an Interior Gateway Protocol (IGP) for the Internet, used to distribute IP routing information throughout a single Autonomous System (AS) in an IP network.
