- 1. IPV6 128 bit hexadecimal address. Includes 8 group Each group of 16 bit Doesnot have the concept of broadcast Does not have the concept of NAT Does not have the concept of Subnetting Ex: fe80:167b:6400:0000:0000:0000:1bac:6701
- 2. Communication Types Unicast One to One transmission Types:- 1. Global Unicast- Public range 2. Unique local- Private range 3. Link local- APIPA Multicast One to Many transmission Anycast One to nearest transmission
- 3. Special IPs Loop back address- ::01 or ::1 Invalid IP- 0000:0000:0000:0000:0000:0000:0000:0000 or :: Multi cast- ff80:: Linklocal- fe80:: Global unicast- 2000:: Unique local- fc00::
- 4. WAN Wide area Networking Types:- Dedicated lines- High cost for implementation High security High speed of 45 mbps Circuit switching Pay according to usage Ex: dial up, ISDN Speed of 128 kbps Packet Switching A virtual communication line or path is established at the time of communication only. Also known as Frame relay. Speed 64kbps- 45mbps
- 5. WAN Protocols HDLC High level data link control Used only for lease line HDLC is enabled by default. It has no user name and password PPP Used for ISDN only It has Authentication Code Router(config)#int serial 1/0 Router(config-if)#encapsulation ppp
- 6. Frame Relay Configuration In Router A Router(conf)#int f0/0 Router(conf-if)#ip address 172.16.0.1 Router(conf)#no shut Router(conf)#int ser1/0 Router(conf)#encapsulation frame-relay Router(conf)#frame-relay interface-dlci 100 Router(conf)# frame-relay lmi-type cisco Router(conf-if)#ip address 40.0.0.1 Router(conf-if)#no shut
- 7. In Router B Router(conf)#int f0/0 Router(conf-if)#ip address 172.17.0.1 Router(conf)#no shut Router(conf)#int ser1/0 Router(conf)#encapsulation frame-relay Router(conf)#frame-relay interface-dlci 200 Router(conf)# frame-relay lmi-type cisco Router(conf-if)#ip address 40.0.0.2 Router(conf-if)#no shut
