INTERNET PROTOCOL v6 Configuration

IPv6 STATELESS Autoconfiguration (SLAAC):

The first router configuration:

R1#config terminal

R1(config)#ipv6 unicast-routing

R1(config)#interface fa0/0

R1(config-if)#ipv6 address fa00:4321:4321:4321::/64 eui-64

R1(config-if)#no shutdown

R1(config-if)#end

For verification:

R1#sh ipv6 interface brief

Change link-local address:

R1(config)#int fa0/0

R1(config-if)#ipv6 address fe80::1 link-local

The second router configuration:

R2#config terminal

R2(config)#int fa0/0

R2(config-if)#ipv6 address autoconfig

R2(config-if)#no shutdown

R2(config-if)#end

Change link-local address:

R2(config)#int fa0/0

R2(config-if)#ipv6 address fe80::2 link-local

For verification:

R2#sh ipv6 interface brief

R2#ping fa00:4321:4321:4321::1

IPv6 STATEFULL Autoconfiguration (Router as DHCP)

R1(config)#ipv6 unicast-routing

R1(config)#interface fa0/0

R1(config-if)#ipv6 address 2001:23::1/64

R1(config-if)#no shutdown

R1(config-if)#exit

R1(config)#ipv6 dhcp pool CCIE

R1(config-dhcp)#dns-server 2001:23::1

R1(config-dhcp)#domain-name malik.com

R1(config-dhcp)#exit

R1(config)#interface fa0/0

R1(config-if)#ipv6 dhcp server CCIE

R1(config-if)#ipv6 nd managed-config-flag (Host should use dhcp for address config)

For verification of DHCP configuration:

R1#show ipv6 dhcp pool

R1#show ipv6 interface fa0/0

Host Router:

R2#config terminal

R2(config)#interface fa0/0

R2(config-if)#ipv6 address autoconfig

R2(config-if)#no shutdown

R2(config-if)#end

For verification of ipv6 address assignment:

R2#show ipv6 interface brief

Change link-local address:

R2(config-if)#ipv6 address fe80::2 link-local

Now check ipv6 address and verify the connectivity:

R2#show ipv6 interface brief

R2#ping 2001:23::1

Configuration of hardware Address (BIA)

R1#config terminal

R2(config)#interface fa0/0

R2(config-if)#mac-address abcd.1111.1111

R2(config-if)#exit

For Verification of BIA:

R2#show interface fa0/0 | include bia
