Figure 5.22 below shows network cables physically connected to an IP phone: ---- ------- ------ ------------------------------ Aggregate Global Unicast Addresses Welcome to what many people find to be one of the hardest areas of the CCNA syllabus to understand. In order to understand IP addressing for the CCNA exam,ccna 200-301 questions and answers, we must cover binary mathematics and the hexadecimal numbering system, classes of addresses, powers of two and rules such as subnet zero, and broadcast and network addresses, as well as formulas to work out subnets and host addresses. You need never concern yourself about running out of host bits per subnet because each subnet has over 18 quintillion hosts. It’s unlikely that any organization would ever run out of subnets, but even if this were the case, another global routing prefix could easily be provided by the ISP. Some of this is already taking place, not only in Europe and the Americas but also in fast-developing countries such as India and China where billions of people live. IPv4 simply isn’t up to the job and even if it was, there aren’t enough addresses to cater for demand. RouterB(config)#int s0/1/0 Route Summarization Prerequisites Enter configuration commands, one per line. End with CNTL/Z. A port that carries data from multiple VLANs is called a trunk. It can use either the ISL or the 802.1Q protocols. A special concept in the 802.1Q world is “native VLAN.” This is a particular type of VLAN in which frames are not tagged. The native VLAN’s purpose is to allow a switch to use 802.1Q trunking (multiple VLANs on a single link) on an interface, but if the other device does not support trunking, the traffic for the native VLAN can still be sent over the link. If a switch receives any untagged traffic over a trunk link, it will assume it is destined for the native VLAN. Cisco uses VLAN 1 as the default native VLAN.
