cisco ccna zarobki.The semantics are similar to the IP Protocol Type field in the IPv4 packet header. If the IPv6 packet contains an extended header ,84 Chapter 1 Network Protocols and Network Device Basicsis, :: can only appear once in an IPv6 address.Take the IPv6 address FE00:0000:0000:0001:0000:0000:0000:0000:0056 as an example. According to the first principle aboveThe IPv6 address can be written as FEOO:O:0:1:0:0:0:0:56.The second principle above applies to groups 2, 3, or 5.7 hexadecimal numbers of the IPv6 address, but not both.apply at the same time. Choosing the latter applies to make the IPv6 address look more concise, as shown below.Figure 1.68 shows an example of an IPv6 packet containing an extended header arranged in a chain. The IPv6 packet header of the first packet in the figure is not followed by any extended headers, because the next header field value in the IPv6 packet header is the IP protocol type code value for TCP. However, the IPv6 packet header of the third packet in the figure is immediately followed by two extension headers: the route extension header and the slice extension header. The next header field value of the slice extension header specifies that it is immediately followed by the TCP header.IPv6 packet header R a header graphene = TCP headerIPv6 Packet Header Routing Extension Header Next Header - TCP Header
