What is a discontiguous subnet?
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 a 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 the difference between contiguous and discontiguous network?
A contiguous network is a network in which packets sent between every pair of subnets pass through subnets of the same network. A discontiguous network is a network in which packets sent between at least one subnet must pass through subnets of a different network.
What happens if I use the wrong subnet mask?
Incorrect Subnet Mask: If a network uses a subnet mask other than the default mask for its address class, and a client is still configured with the default subnet mask for the address class, communication will fail to some nearby networks but not to distant ones.
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 mask?
May 19, 2010 by Tony Mattke 19 comments. Unlike subnet masks, wildcard masks allow you to use discontiguous bits which enable you to match on a range of values. Using these within routing protocols is typically frowned upon, if not outright prohibited.
What is the main disadvantage of using RIPv1?
Disadvantage of RIP ver1 – Bandwidth utilization is very high as broadcast for every 30 seconds. It works only on hop count. It is not scalable as hop count is only 15. If there will be requirement of more routers in the network it would be a problem .
Why is RIPv2 better than RIPv1?
RIPv1 uses classful routing. The periodic routing updates do not carry subnet information, lacking support for variable length subnet masks (VLSM)….Differences between RIPv1 and RIPv2 :
| SR.NO | RIPv1 | RIPv2 |
|---|---|---|
| 5. | It does not support for VLSM and discontinuous networks. | It supports for VLSM and discontinuous networks. |
| 6. | It is less secure. | It is more secure. |
Should I change my subnet?
Why do we change a Subnet Mask? It is a recommended procedure for increasing a DHCP scope when the current scope has entirely consumed the current subnet mask. However, this method requires you to change all subnet hosts and gateways.
What is the subnet mask that is most often used between a point to point connection between two routers?
31-bit subnet mask
A 31-bit subnet mask is often used for an interface that is the endpoint of a point-to-point network.
Why do we use wildcard mask?
The quick definition: A wildcard mask allows or denies all the traffic from a network IP address. The wildcard mask tells the router which bits in the IP address need to match the access list and which do not.
