What routing protocol supports VLSM?
In order to use VLSM, a network administrator must use a routing protocol that supports it. Cisco routers support VLSM with Open Shortest Path First (OSPF), Integrated Intermediate System to Intermediate System (Integrated IS-IS), Enhanced Interior Gateway Routing Protocol (EIGRP), RIP v2, and static routing.
Which classless routing protocol supports VLSM and CIDR?
RIPv2
RIPv2 – classless – sends subnet mask in the routing updates, thus supporting VLSM and CIDR. Like RIPv1, RIPv2 is a distance vector routing protocol.
What is classful and classless routing protocol?
Classful or classless (use of VLSM): Classful routing protocols do not include the subnet mask and cannot support variable-length subnet mask (VLSM). Classless routing protocols include the subnet mask in the updates. Classless routing protocols support VLSM and better route summarization.
What is the advantage of VLSM over classful subnetting?
Because a mask defines the size of the subnet (the number of host addresses in the subnet), VLSM allows engineers to better match the need for addresses with the size of the subnet.
What is the purpose of VLSM?
VLSM is a subnet design strategy that allows all subnet masks to have variable sizes. In VLSM subnetting, network administrators can divide an IP address space into subnets of different sizes, and allocate it according to the individual need on a network.
Which statement is true regarding classless routing protocols?
Which statement is true regarding classless routing protocol? Explanation: Use of variable length subnet masks is permitted in classless routing protocols. Also use of discontinuous networks is allowed in such routing protocols.
What are classless routing protocols?
Classless routing protocols do send the subnet mask with their updates. Thus, Variable Length Subnet Masks (VLSMs) are allowed when using classless routing protocols. Examples of classful routing protocols include RIPv1 and IGRP. Examples of classless routing protocols include RIPv2, EIGRP, OSPF, and IS-IS.
What is the meaning of VLSM?
Variable Length Subnet Mask
Variable Length Subnet Mask (VLSM) is a subnet — a segmented piece of a larger network — design strategy where all subnet masks can have varying sizes. This process of “subnetting subnets” enables network engineers to use multiple masks for different subnets of a single class A, B or C network.
Is VLSM classful or classless?
By definition, classless routing protocols advertise the mask with each advertised route, and classful routing protocols do not.” i.e. RIP-2, EIGRP, or OSPF support VLSM, and are considered classless.
Is VLSM Classful or classless?
Which statement explain Classes routing protocols?
Which is an example of a classless routing protocol?
Thus, Variable Length Subnet Masks (VLSMs) are allowed when using classless routing protocols. Examples of classful routing protocols include RIPv1 and IGRP. Examples of classless routing protocols include RIPv2, EIGRP, OSPF, and IS-IS.
What kind of router do I need for VLSM?
VLSM is supported by the following protocols: Open Shortest Path First (OSPF), Enhanced Interior Gateway Router Protocol (EIGRP), Border Gateway Protocol (BGP), Routing Information Protocol (RIP) version 2 and 3, and Intermediate System-to-Intermediate System (IS-IS). You need to configure your router for VLSM with one of those protocols.
What’s the difference between classless routing and Hello messages?
In classless routing, hello messages are used for checking status. In classless routing, subnet mask is not same throughout, it may vary for all devices, we can see it in the given picture. Let’s see that the difference between classful routing and classless routing:
What’s the difference between classless routing and CIDR?
In classless routing, VLMS (Variable Length Subnet Mask) is supported and also CIDR (Classless Inter-Domain Routing). In classless routing, hello messages are used for checking status. In classless routing, subnet mask is not same throughout, it may vary for all devices, we can see it in the given picture.
