1. Introduction to IPv6

IPv6 addresses are 128 bits long, with a total of 2 ^ 128 addresses.

IPv6 address format: x:x:x:x:x:x:x:x, where x is hexadecimal.

IPv6 simplification:

2001:0DB8:010F:0001:0000:0000:0000:0D0C removes leading 0

2001: DB8:10F: 1: 0: 0: 0: D0C multiple consecutive zeros can be replaced by::

2001: DB8:10F: 1:: D0C

2001:0DB8:0000:0000:FFFF:0000:0000:0D0C

Can be expressed as

2001:DB8::FFFF:0:0:0D0C or 2001:0DB8:0:00:FFFF::0D0C

But it cannot be expressed as

2001:0DB8::FFFF::0D0C

Because I don't know how many zeros are represented by the two:: respectively.

Example:

FF02:0:0:0:0:0:0:1 FF02::1

FF15:0:0:0:0:0:1:C001 FF15::1:C001

0:0:0:0:0:0:0:1:: 1

0:0:0:0:0:0:0:0::

IPv6 accesses web pages by address format: http://[2001:DF0:1003::F]:8080/index.html

IPv6 address classification

Unicast Unicast (one to one)

Aggregate Global Unicast Addresses (public network) 2000 VuGV 3

Link-local Addresses FE80::/10

Site-local Addresses (private network) FEC0::/10

Unspecified:: / 128

Loopback:: 1/128

IPv4 compatible directly converts decimal to hexadecimal

Multicast Multicast (one-to-many) FF00::/8

Anycast Anycast (nearest pair)

EUI-64 (assuming the MAC address is 00:90:27:17:FC:0F)

Step 1: split the MAC address in two and insert FFFE in the middle

00:90:27:FF:FE:17:FC:0F

Part II: interchange the seventh bit 0 and 1 of the first byte

00000000:90:27:FF:FE:17:FC:0F

00000010:90:27:FF:FE:17:FC:0F

02::90:27:FF:FE:17:FC:0F

The last 24 bits of the Solicited-Node Multicast Address FF02::1:xx:xxxx are the last 24 bits of the IPv6 unicast address

Each IPv6 unicast address corresponds to an Solicited-Node Multicast Address address

The next hop of the route is Link-local Addresses.

3. IPv6 configure Link-local Addresses address (FE80::/10)

R1 configuration

Interface FastEthernet0/0

Ipv6 enable

R2 configuration

Interface FastEthernet0/0

4. IPv6 is configured with Aggregate Global Unicast Addresses (2000 VRV)

R1 configuration

Interface FastEthernet0/0

Ipv6 address 2000::1/64

R2 configuration

Interface FastEthernet0/0

Ipv6 address 2000::2/64
