IPV6 configure ip and connectivity verification : Lab 1

Requirement:

• show mac address of interface
• change mac address of interface
• Configure link local ipv6 addresses on interfaces
• ping and check connectivity

---

! ipv61 configuration

hostname ipv61
interface FastEthernet0/0
 mac-address bcde.9988.22aa
 no shutdown
 ipv6 enable

! ipv62 configuration

hostname ipv62
interface FastEthernet0/0
mac-address dcaa.4433.0066
 no shutdown
 ipv6 enable

Verification:

ipv61#show interface fastEthernet 0/0 ;
FastEthernet0/0 is administratively down, line protocol is down
  Hardware is Gt96k FE, address is c400.1ad4.0000 (bia c400.1ad4.0000)

Note: Compare both addresses mentioned above. Both are same. We have checked this before giving mac-address command to router

After giving mac-address bcde.9988.22aa command to router

------------------------------------------------------------------------------------------------------------------------------------------------

ipv61(config-if)#mac-address bcde.9988.22aa

ipv61#sh int f0/0
FastEthernet0/0 is administratively down, line protocol is down
  Hardware is Gt96k FE, address is bcde.9988.22aa (bia c400.1ad4.0000)

Note: Compare both addresses mentioned above. Both are now different
