NightShade1 wrote: They are not the same.... CIDR is supernetting Well in other words the difference between CIDR and route summarization is that route summarization is generally done within, or up to, a classful boundary, whereas CIDR combines several classful networks(this is the key) For a detailed explanation just google yourself tho.... BTW you can turn off the auto-summary in rip v2....

There is nothing like giving other people confusing and mish mosh answers. Sometimes it's better to say you don't know instead of giving other people wordy false answers. Did you read his post? It was completely wrong. Route summarization is supernetting! I try not to BS my way through life. With technology most of the time you either know it or you don't. Good luck -Ciscopimpenator
Classless Interdomain Routing (CIDR) A method supported by classless routing protocols, such as OSPF and BGPv4, that allows a group of IP networks to appear to other networks as a unified, larger entity. CIDR is based on the concept of ignoring the IP class of address and permitting route aggregation and VLSMs. This enables routers to combine routes in order to minimize the routing information that needs to be conveyed by the primary routers.
Route summarization is the process of advertising a large number of networks with one route entry. Route summarization is automatically turned on with RIP, IGRP, and EIGRP. You need to turn off auto-summarization if you have discontiguous networks or if you want to configure manual summarization.
Supernetting, which is also called summarization, is the process of combining networks to save routing table entries. For example, it is typically more efficient to advertise 172.16.0.0 instead of 254 subnets, starting with 172.16.1.0 going to 172.16.254.0.

NightShade1 wrote: The only one confused here its you my explanation seems pretty clear to me but whatever... could be KIND of summarization but they are not the same its like comparing apples and orange and saying they are the same because they are fruits O_o CIDR is moving talking the network address to the left of the neutral major network If we have 172.16.1.0/24 we know its a class B and the neutral mask is /16 if i want to use the CIRD then i will want to make the mask less than /16 if we were summarizing then we would want a mask greater than /16 but less than /24 They are just not the same, they do have differneces. If you were soo sure of what you saying guess you wouldnt be asking this in first place... If they were the same there wouldnt have any difference in first place and there are!!! Anyways ill put it to you in simple words so you can understand it. Address agregation takes summarization a step further by breaking the class limits of the major networks addresses when the summarization which is what we taking about here dont break those limits! they are limited to that class limit and thats why in the example i gave up the summarization must be higher /16 but smaller than /24 In both case yeah both reduce the length of the address maskModerated If you dont want to listen me fine go and BS yourself way through life heh

You are completely wrong. Go read the BSCI book or go on wikipedia and read CIDR and route summarization.

No, they are not the same.... the both reduce the lenght of address mask but one break the class limits of the major network address and the other doesnt..... supernetting = summarization supernetting does not equal CIDR, like you said earlier WTF are class limits? Most people say classful or classless, not class limits. CIDR uses summarization. CIDR is a concept of keeping routing tables small by allocating IP addresses properly. I learned this today because I did some major research. I'm just letting you know because you are wrong and this is an important concept. -Ciscopimpenator

Nightshade has tried to explain summarization is to the right of the major network boundary while supernetting i.e. CIDR is to the left of the major boundary. This concept has been explained many times in this forum by myself and others, maybe you should use the search engine before you start the insults.
