What is a discontiguous network?

What is a discontiguous network?

– Discontiguous network: A classful network in which packets sent between at least one pair of subnets must pass through subnets of a different classful network. Autosummarization prevents an internetwork with a discontiguous network from working properly.

What is Discontiguous?

Not contiguous in space; not touching or adjacent; disconnected, separate. Also: consisting of non-adjacent parts; characterized by spatial discontiguity.

What is non contiguous network?

0.0. 172.16. 0.0 is a discontiguous network.” I cannot find any reference, on Cisco.com, to the term “non-contiguous”. Non-contiguous is a term used to describe subnetting which doesn’t use contiguous ones, from left to right, in a subnet mask.

What is a contiguous IP?

A network is contiguous if you can get from every part of that network to every other part of that network without going outside of the network.

What is a discontiguous subnet?

Discontiguous subnets means that to go from one subnet of a network to another subnet of that network you must go through subnets of a different network. For example if you are in subnet 10.10. 10.0 and to get to 10.30. 30.0 you must go through 172.16. 10.0 then that would be discontiguous.

Can Discontiguous network work with RIPV1?

Therefore, RIPV1 is able to support discontiguous networks. You can make this topology work, as shown in Figure 6-10, using a Cisco router. One method to accomplish this is to configure a secondary address, as shown in Figure 6-10.

What is non contiguous?

Noncontiguous describes something–usually land–that is not connected and does not share a border. For example, the contiguous United States comprises 48 states and excludes Alaska and Hawaii. Alaska and Hawaii are thus considered noncontiguous states.

What is CIDR in networking?

CIDR (Classless Inter-Domain Routing) — also known as supernetting — is a method of assigning Internet Protocol (IP) addresses that improves the efficiency of address distribution and replaces the previous system based on Class A, Class B and Class C networks.

Which one is not a contiguous mask?

Which one is not a contiguous mask? Explanation : None. 1. An IPv4 address consists of _______ bits.

Which statement is correct in RIPv2?

Solution(By Examveda Team) RIPv2 is pretty much just like RIPv1. It has the same administrative distance and timers and is configured just like RIPv1.

Does Eigrp support discontiguous networks?

Unlike IGRP, EIGRP is an advanced distance vector protocol that carries the subnet mask information when an update is sent out. Therefore, EIGRP supports discontiguous network and variable-length subnet masking (VLSM).

What is the difference between contiguous and noncontiguous?

In contiguous memory allocation, swapped-in processes are arranged in the originally allocated space. In non-contiguous memory allocation, swapped-in processes can be arranged in any place in the memory.

What is an example of contiguous?

1. The definition of contiguous is two things that are connected or touching along one side. An example of contiguous is how Chile shares a border with Argentina.

What is CIDR and subnetting?

A system called Classless Inter-Domain Routing, or CIDR, was developed as an alternative to traditional subnetting. The idea is that you can add a specification in the IP address itself as to the number of significant bits that make up the routing or networking portion.

What does RIPv2 used to prevent routing loops?

RIPv2 uses the same timers and loop-avoidance schemes as RIPv1. Split horizon is used to stop an update from being sent out the same interface it was received on. Holddown timers allow time for a network to become stable in the case of a flapping link.

What is the metric used for RIPv2?

RIPv2 uses the same routing metric as RIPv1, hop count. Hop count is the number of routers between a source and destination. RIPv2 also has the same hop count limit as RIPv1. If a route has more than 15 hops, the route will be discarded as invalid.

Which command will need to be configured for support of discontiguous networks?

8.0/24 to Router A, which will ignore this route advertisement. To make EIGRP support discontiguous networks, you must configure the no auto-summary command under the command router eigrp.
