After successfully determining that the routing process is enabled, the next step is to analyze the routing table and see whether the information listed there is valid. Some of the points you should focus on include: unicast-flood Disabled this to indicate that a route is no longer reachable. This is accomplished by setting the route metric to a maximum value. Classful protocols can’t use VLSM (i.e., RIPv1 and IGRP, which are no longer in the CCNA syllabus). This is because they don’t recognize anything other than default network masks due to being developed prior to VLSM. Spend 15 minutes on the subnetting.org website !!!!! Clock is synchronized, stratum 6, reference is 10.0.0.1 Split horizon mandates that routing information cannot be sent back out of the same interface through which it was received. This prevents the re- advertising of information back to the source from which it was learned. While this characteristic is a great loop prevention mechanism, it is also a significant drawback, especially in hub-and-spoke networks. In order to understand how floating static routes work, you first need to learn (or be reminded of) the administrative distance (AD) attribute of the routes. Each type of route is assigned a numerical value that tells the router which route should be preferred. The lower the number, the stronger the candidate for insertion into the routing table. 1.Add VLAN2 to the switches. 　　Minimum = 0ms, Maximum = 1ms, Average = 0ms C:\>ping 10.20.20.1 %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to down Switch# 192.168.1.10. The WAN provider “Low Latency Networks” provides much better round-trip times than the WAN provider “Slow as You Go WAN Solutions.” Although you still want to load balance all traffic to the 192.168.1.0/24 network, when users communicate with the latency-sensitive server 192.168.1.10, you want that traffic to use the Low Latency Network circuit. ACL Rule 1 – Use only one ACL per interface per direction.

Cisco have addressed this in the new exam syllabus. The ICND1 exam requires you to have an understanding of basic routing and packet flow across a network. We will also take a look at the technology behind routing protocols. It is important to note that routing protocols DO NOT send packets across the network. Their role is to determine the best path for routing. Routed protocols actually send the data, and the most common example of a routed protocol is IP. Walkthrough Switch#show cdp neighbors The easy way to perform wildcard masking for the CCNA exam is simply to ensure that you add a number to the subnet mask to give you a total of 255. So, if your subnet mask in one octet was 192, you would add 63 to it to make Cisco documentation advises us to put an EXTENDED ACL as close to the SOURCE as possible and STANDARD ACL as close to the DESTINATION as possible,350-801 clcor exam topics, because that will prevent unnecessary overhead but will still allow any “legitimate” traffic.

When convergence takes a long time to occur, intermittent packet loss and loss of connectivity may be experienced between remote networks. In addition to these problems, slow convergence can result in network routing loops and outright network outages.

Here is an example of configuring a gateway of last resort using the ip route 0.0.0.0 0.0.0.0 command: Like load, the term reliability means different things depending upon the context in which it is used. Here, unless stated otherwise, it should always be assumed that reliability refers to the dependability of network links or interfaces. In Cisco IOS software, the reliability of a link or interface is represented as a fraction of 255. For example, a reliability value of 255/255 indicates that the interface is 100% reliable. Similar to the interface load, by default the reliability of an interface is calculated as an average over a period of five minutes.
