Router Solicitation messages are sent by hosts when interfaces are enabled for IPv6. These messages are used to request that routers on the local segment generate RA messages immediately, rather than at the next scheduled RA interval. Figure 3.12 below illustrates a wire capture of an RS message: address used to test whether TCP/IP is working on your device. In the exam, they may well try to trick you by adding broadcast addresses as options for host addresses, or even subnet addresses for host addresses. This is why you need to be able to identify which is which. You will also come across the same issue on live networks, where other engineers have tried to add the wrong address to an interface. ------ ----- ----- ---------- --------------- 0 output buffer failures, 0 output buffers swapped out and troubleshooting is outside the syllabus. Bear in mind that the firewall could be the cause of network issues and, in particular, packet loss because its job is to filter packets. If ICMP is blocked by your firewalls, it will prevent you from using the ping command as part of your troubleshooting. If you use the design section of the Subnetting Secrets cheat sheet, you will see which mask gives you 30 hosts: Decimal = 21 Switch Ports Model SW Version SW Image Switch2(config)#interface fa0/15 Cisco IOS Software, 1841 Software (C1841-ADVIPSERVICESK9-M), Version 12.4(15)T1, RELEASE SOFTWARE (fc2) Received 956 broadcasts, 0 runts, 0 giants, 0 throttles Route Summarization 0000:0000:0000:0000:0000:0000:0000:0001 If you were to check the Ethernet frame, you would see the broadcast address in hexadecimal, which is the Destination field filled with Fs in Figure 2.3 below: used only once, no matter which mask it has. 10 Force 10 Mbps operation Prefix advertisement The ZIP code system was devised to make the routing of mail more accurate and efficient. For example, the sorting office in Atlanta doesn’t need to know which street in San Francisco the packet is destined for. Having to store that information would make the sorting process unworkable. 2.Add the below IPv6 address to F0/0 on R1. For R2 add the :2 address. Make sure you no shut the interfaces. Domain: a specific part of a network Layer 6 – Presentation Layer Binary = 10110101 Before the data can be passed across the network, the Transport Layer needs to establish how much data can be sent to the remote device. This will depend upon the speed and reliability of the link from end to end. If you have a high- speed link but the end-user has a low-speed link, then the data will need to be sent in smaller chunks. I know we haven’t covered VLANs yet, but for now, consider a VLAN a logical Local Area Network where devices could be anywhere on the network physically but, as far as they are concerned, they are all directly connected to the same switch. In the configuration below, by default, all ports on the switch are left in VLAN 1: You can see that each numbering system starts with a zero,ccna 200 301 cbt nuggets, so: via FE80::20C:CEFF:FEA7:F3A0, FastEthernet0/0 ------ ----- ----- ---------- --------------- That is enough subnetting for now. We will revisit this subject many times over. For some network design examples using the lower part of the chart, please check out resources on passhot.com. If a ping through the switch is unsuccessful, then check to ensure that the end devices are in the same VLAN. Each VLAN is considered a network and for this reason must have a different address range from any other VLAN. In order for one VLAN to reach another, a router must route the traffic. Class A = 255.0.0.0 Class B = 255.255.0.0 Class C = 255.255.255.0 Current configuration : 1091 bytes! version 12.1 While one of the advantages of IPv6 is stateless autoconfiguration capability, stateful autoconfiguration still provides several advantages, which include the following: Exercise 1: Write out the binary equivalents for the addresses below, and then determine which bits match. I have written the first two octets for you to save time. IPv6 stateless autoconfiguration Router redirection Subnetting with IPv6 64016384 bytes total (60957660 bytes free) SwitchA# 200.100.2.0 Purpose 10.255.255.255 As was stated earlier in this module, IPv6 allows multiple prefixes to be configured on the same interface. If multiple prefixes have been configured on the same interface, the show ipv6 interface [name] prefix command can be used to view all assigned prefixes as well as their valid and preferred lifetime values.
