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 (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 (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…

Types of IPv6 Unicast Addresses (33.1.3)An IPv6 unicast address uniquely identifies an interface on an IPv6-enabled device. A packet sent to a unicast address is received by the interface that is assigned that address. Similar to IPv4, a source IPv6 address must be a unicast address. The destination IPv6 address can be either a unicast…

Objectives Upon completion of this chapter, you will be able to answer the following questions: • What is the operation of IPv6 neighbor discovery? Key Terms There are no new terms in this chapter. Introduction (34.0) Webster here! Halimah is still investigating her company’s network. She is impressed with the way the IT team has…

Introduction to an IPv4 Routing Table (32.2.6)Notice in Figure 32-10 that R2 is connected to the internet. Therefore, the administrator configured R1 with a default static route sending packets to R2 when there is no specific entry in the routing table that matches the destination IP address. R1 and R2 are also using OSPF routing…

Static routes are route entries that are manually configured. Figure 32-6 shows an example of a static route that was manually configured on router R1. The static route includes the remote network address and the IP address of the next hop router. Figure 32-6 Static Routing Example If there is a change in the network…

This topic will introduce the role of the router in the routing process and an introduction their use of routing tables for forward packets. Router Packet Forwarding Decision (32.2.1) The previous topic discussed host routing tables. Most networks also contain routers, which are intermediary devices. Routers also contain routing tables. This topic covers router operations…

Default Gateway (32.1.2) The default gateway is the network device (i.e., router or Layer 3 switch) that can route traffic to other networks. If you use the analogy that a network is like a room, then the default gateway is like a doorway. If you want to get to another room or network you need…
