1 Understanding IPv6 Slide: 1 Appendix A Link-Layer Support for IPv6

2 Understanding IPv6 Slide: 2 Lesson Objectives Basic structure of IPv6 packets LAN media WAN media IPv6 over IPv4

3 Understanding IPv6 Slide: 3 IPv6 Header Payload IPv6 Packet Link-Layer Frame Link-Layer Header Link-Layer Trailer Basic Structure of IPv6 packets

4 Understanding IPv6 Slide: 4 LAN Media Ethernet Token Ring FDDI

5 Understanding IPv6 Slide: 5 Destination Address Source Address IPv6 Packet... EtherType Frame Check Sequence Preamble ,500 bytes = 0x86DD Ethernet II Encapsulation of IPv6 Packets

6 Understanding IPv6 Slide: 6 Destination Address Source Address DSAP SSAP Control IPv6 Packet Length Frame Check Sequence Preamble IEEE LLC Header Start Delimiter... IEEE Header IEEE Trailer Organization Code EtherType = 0 = 0x86DD SNAP Header 38-1,492 bytes = 0xAA = 0x3 Ethernet IEEE SNAP Encapsulation of IPv6 Packets

7 Understanding IPv6 Slide: 7 Frame Status IEEE Header IEEE Trailer Starting Delimiter Access Control Frame Control Destination Address Source Address Frame Check Sequence Ending Delimiter DSAP SSAP Control IPv6 Packet IEEE LLC Header... Organization Code EtherType = 0x0 = 0x86DD SNAP Header = 0xAA = 0x3 IEEE SNAP Encapsulation of IPv6 Packets

8 Understanding IPv6 Slide: 8 FDDI Header FDDI Trailer Preamble Starting Delimiter Frame Control Destination Address Source Address Frame Check Sequence Ending Delimiter Frame Status DSAP SSAP Control IPv6 Packet IEEE LLC Header... Organization Code EtherType = 0x0 = 0x86DD SNAP Header = 0xAA = 0x3 Up to 4,352 bytes FDDI Encapsulation of IPv6 Packets

9 Understanding IPv6 Slide: 9 WAN Media Point-to-Point Protocol (PPP) X.25 Frame Relay ATM

10 Understanding IPv6 Slide: 10 Flag Address Control Protocol IPv6 Packet Frame Check Sequence Flag = 0x7E = 0xFF = 0x3 = 0x57 = 0x7E... PPP with HDLC Framing Encapsulation of IPv6 Packets

11 Understanding IPv6 Slide: 11 Flag Address Control = 0x7E... General Format Indicator Logical Channel Number Packet Type Identifier Frame Check Sequence Flag IPv6 Packet = 0x7E PLP Header LAPB Header and Trailer NLPID = 0x8E X.25 Encapsulation of IPv6 Packets

12 Understanding IPv6 Slide: 12 Flag Address Control = 0x7E... Frame Check Sequence Flag IPv6 Packet = 0x7E NLPID = 0x8E = 0x3 Frame Relay Encapsulation of IPv6 Packets

13 Understanding IPv6 Slide: 13 IPv6 Packet Padding User to User Indication Common Part Indicator Length of Payload Frame Check Sequence bytes... Up to 9,180 bytes... AAL5 Trailer ATM Null Encapsulation of IPv6 Packets

14 Understanding IPv6 Slide: 14 IPv6 Packet Padding User to User Indication Common Part Indicator Length of Payload Frame Check Sequence bytes... DSAP SSAP Control Organization Code EtherType =0xAA =0x3 =0 =0x86DD LLC Header SNAP Header AAL5 Trailer ATM SNAP Encapsulation of IPv6 Packets
