Is OSPF a classful or classless link-state routing protocol?
OSPF is a classless link-state routing protocol. RIP version 1 and IGRP are both classful distance vector routing protocols, EIGRP is a hybrid protocol that supports classless addressing.
What is the characteristic of classful routing?
Classful routing protocols do not carry subnet mask information on their routing updates. This makes them unsuitable for hierarchical addressing that require Variable Length Subnet Mask (VLSM) and discontiguous network. Classless routing protocols do carry subnet mask information on their routing updates.RIP v1 and IGRP are classful routing protocols. RIP v2, EIGRP, OSPF, and BGP are classless routing protocol.When running a classful routing protocol on a network, make sure you use the same subnet mask everywhere. Otherwise, routing black holes can occur.Classless routing protocols extend the standard Class A, B, or C IP addressing scheme by using a subnet mask or mask length to indicate how routers must interpret an IP network ID. Classless routing protocols include the subnet mask along with the IP address when advertising routing information. Subnet masks representing the network ID are not restricted to those defined by the address classes, but can contain a variable number of high-order bits. Such subnet mask flexibility enables you to group several networks as a single entry in a routing table, significantly reducing routing overhead. Classless routing protocols includes RIP v2 and OSPF, Border Gateway Protocol version 4 (BGP4) and Intermediate System to Intermediate System (IS-IS).
What is IGP?
Dear All, Clasful routing protocols will not support VLSM because it doesn't send the subnet mask information along with routing information. Classless routing protocols will support VLSM as because it s sending the subnet mask information with routing updates. Regards, Sivaraj C
How does a dynamic route get into a routing table?
Routing is the process that direct a packet to choose an optimal path from source to destination. Routing is of two types static routing and dynamic routing . Dynamic routing is not done manually and uses a number of protocols , it is automatic.
Which routing protocol excludes the subnet information from routing updates?
RIP VERSIONV1 can be seen to exclude subnet information from routing updates, this is because ripv1 is a classful routing protocol and does not support VSLM, this was corrected in RIPv2 where ripv2 does send out subnet mask's in the form of a prefix eg /24 which is the subnet mask of 255.255.255.0 or a class c address.
What characteristic defines the difference between classful and classless routing protocols?
Classless protocols send a subnet mask with each route advertisement
What do you mean by classless addressing?
CLASSFUL ROUTING PROTOCOL. It means it will not carry the routing mask information while routing updates or routing advertisements. it will carry just only the ip-address information's. It will assume just default mask information's. Example : class-A 255.0.0.0 Class-B 255.255.0.0 Class-C 255.255.255.0 So classful routing protocols will not support the VLSM and Supernetting Example of classful routing protocols is 1. RIP V1 2. IGRP CLASSLESS ROUTING PROTOCOL These kind of routing protocols will carry the subnet mask information's while doing the routing updates or routing advertisements. So it will support the VLSM and Supernetting, also support noncontiguous networks Example RIP V2 EIGRP OSPF CLASSFUL ROUTING PROTOCOL. It means it will not carry the routing mask information while routing updates or routing advertisements. it will carry just only the ip-address information's. It will assume just default mask information's.

Is OSPF a classful or classless link-state routing protocol?
OSPF is a classless link-state routing protocol. RIP version 1 and IGRP are both classful distance vector routing protocols, EIGRP is a hybrid protocol that supports classless addressing.
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 action will enable classful routing behavior?
Using only classful netmasks on all networks
Which type of routing protocol does not send subnet mask information in the routing updates A. Linkful B. Stateful C. Classful D. Classless Which one is it?
Classful.
What is a protocol does not include subnet mask information in its messages?
Classful Routing Protocol
What is the differences between routing and routed protocols?
Routing protocols are used by routers (RIP, EIGRP, OSPF) Routed protocols are the actual protocols on the wire (TCP/IP)
Which technology can be used in distance vector routing protocols to prevent routing loops?
Which two technologies can be used in distance vector routing protocols to prevent routing loops?
What is Distance Vector protocols?
Distance vector protocols are routing protocols that use the distance and direction to a destination network to make routing decisions. Examples include RIP (Routing Information Protocol) and EIGRP (Enhanced Interior Gateway Routing Protocol). These protocols share routing information with neighboring routers and update their routing tables based on the information received.
