What Did I Learn in This Chapter? – Cisco 100-150 Study Course
Summary (33.6) The following is a summary of each topic in the chapter and some questions for your reflection. What Did I Learn in This Chapter? (33.6.1) • IPv6 Address Types—There are three types of IPv6 addresses: unicast, multicast, and anycast. IPv6 does not use the dotted-decimal subnet mask notation. Like IPv4, the prefix length…
IPv6 Multicast Addresses – Cisco 100-150 Study Course
This section introduces the two types of IPv6 multicast addresses: well-known multicast and solicited-node multicast addresses. Assigned IPv6 Multicast Addresses (33.5.1) Earlier in this chapter, you learned that there are three broad categories of IPv6 addresses: unicast, anycast, and multicast. This section goes into more detail about multicast addresses. IPv6 multicast addresses are similar to…
Randomly Generated Interface IDs – Cisco 100-150 Study Course
Depending upon the operating system, a device may use a randomly generated interface ID instead of using the MAC address and the EUI-64 process. Beginning with Windows Vista, Windows uses a randomly generated interface ID instead of one created with EUI-64. Windows XP and previous Windows operating systems used EUI-64.After the interface ID is established,…
EUI-64 Process vs. Randomly Generated
EUI-64 Process vs. Randomly Generated (33.3.5) When the RA message is either SLAAC or SLAAC with stateless DHCPv6, the client must generate its own interface ID. The client knows the prefix portion of the address from the RA message, but must create its own interface ID. The interface ID can be created using the EUI-64…
Method 1: SLAAC – Cisco 100-150 Guide
Method 1: SLAAC (33.3.2)Stateless Address Autoconfiguration (SLAAC) is a method that allows a device to create its own GUA without the services of DHCPv6. Using SLAAC, devices rely on the ICMPv6 RA messages of the local router to obtain the necessary information.By default, the RA message suggests that the receiving device use the information in…
Dynamic Addressing for IPv6 GUAs
Dynamic Addressing for IPv6 GUAs (33.3)This section discusses the different methods of how a device can automatically create or receive an IPv6 GUA.RS and RA Messages (33.3.1)If you do not want to statically configure IPv6 GUAs, no need to worry. Most devices obtain their IPv6 GUAs dynamically. This topic explains how this process works using…
Static GUA Configuration on a Windows Host
Static GUA Configuration on a Windows Host (33.2.2) Manually configuring the IPv6 address on a host is similar to configuring an IPv4 address. As shown in Figure 33-8, the default gateway address configured for PC1 is 2001:db8:acad:1::1. This is the GUA of the R1 GigabitEthernet interface on the same network. Alternatively, the default gateway address…
IPv6 LLA – Cisco 100-150 Guide
IPv6 LLA (33.1.7)An IPv6 link-local address (LLA) enables a device to communicate with other IPv6-enabled devices on the same link and only on that link (subnet). Packets with a source or destination LLA cannot be routed beyond the link from which the packet originated.The GUA is not a requirement. However, every IPv6-enabled network interface must…
IPv6 GUA Structure
IPv6 GUA Structure (33.1.6) Global Routing Prefix The global routing prefix is the prefix, or network, portion of the address that is assigned by the provider, such as an ISP, to a customer or site. For example, it is common for an ISP to assign a /48 global routing prefix to its customers. The global…
