Re: IPV6 - Basic

Here is the Procedure,
Use Site-local address : means Address will start with FEC0

so the Network part will be FEC0:0000:0000:0000

Now, Calculating host part,

Lets say ,we have IPv4 addresses as

192.168.1.1 and 192.168.1.6

these addresses have to be used as Host part in the IPv6 Address (acc to Q)

So converting them into HEX

192 = 11000000 = C0
168 = 10101000 = A8
1 = 00000001 = 01
6 = 00000110 = 06

since we are having /64 prefix, and as a matter of fact that Host part
contains 64 bits so we add 0000:0000

hence host part for R1 will be

0000:0000:C0A8:0101

and for R6

0000:0000:C0A8:0106

hence, the resulting full addresses will be

For R1 : FEC0:0000:0000:0000:0000:0000:C0A8:0101 = FEC0::C0A8:0101
For R6 : FEC0:0000:0000:0000:0000:0000:C0A8:0106 = FEC0::C0A8:0106

so you would configure like this;

R1:
interface s0/0
ipv6 address FEC0::C0A8:0101

R6:
interface s0/1
ipv6 address FEC0::C0A8:0106
