IP v6 : How to convert IPv4 to IPv6

IPv6 is 128 bit hexadecimal addressing scheme .
ex- 2001: B82C:1234:0000::DA55:0000:0000:ABCD


To enable IPv6 on a particular interface ,we should give some commands to enable it :


R1(config)#int e 0  :- on the ethernet 0 port 
R1(config-if )# ipv6 add 2004:abcd:1234:0001::/64 eui-64 :- particular address which has to be enable 
R1(config-if )# ipv6 rip 1 enable
R1(config-if )# no shutdown 


now on serial interface 0

R1(config)#int s 0  :- on the serial 0 port 
R1(config-if )# ipv6 add 2005:abcd:1234:0002::/64 eui-64 :- particular address which has to be enable 
R1(config-if )# ipv6 rip 1 enable
R1(config-if )# no shutdown 


now we have to give same commands on Router 2 
R2(config)# ipv6 unicast-routing (to enable routing in IPv6 )

R2(config)#int e 0  :- on the ethernet 0 port 
R2(config-if )# ipv6 add 2003:abcd:1234:0001::/64 eui-64 :- particular address which has to be enable 
R2(config-if )# ipv6 rip 1 enable
R2(config-if )# no shutdown 




now on the serial port 0 of another side 



R2(config)#int s 0  :- on the serial 0 port 
R2(config-if )# ipv6 add 2005:abcd:1234:0002::/64 eui-64 :- particular address which has to be enable 
R2(config-if )# no shutdown 
R2(config-if )# ipv6 rip 1 enable
R2(config-if )# clock rate 64000  ( clock rate is always givento D.C.E. side )



Some commands to check the interface address : - 


R2# sh ipv6 int brief 


R2# sh ipv6 int e0 


R2# sh ipv6 route
