IPv6 Address Autoconfiguration and EUI-64 Addressing on Cisco Routers
Objective
Learn and understand how to configure IPv6 addresses on Cisco routers using address autoconfiguration and EUI-64 addressing.
Purpose
Configuring IPv6 addressing is a fundamental task for any Cisco engineer. You must be prepared to configure an IPv6 address using Stateless Address Autoconfiguration (SLAAC) and EUI-64 addressing.
Lab Topology
Use the following topology to complete this lab exercise:
![Router Setup 1](/static/labs/cisco/CCNA_200-301/lab5/1.png)
Task 1: Configure Hostnames
Objective: Set hostnames on routers R1 and R3 as per the topology.
Configuration Steps:
Router#config t Enter configuration commands, one per line. End with CTRL/Z. Router(config)#hostname R1 Router#config t Enter configuration commands, one per line. End with CTRL/Z. Router(config)#hostname R3 R3(config)#
Task 2: Configure GigabitEthernet and Loopback Interfaces
Objective: Configure the IP addresses on the GigabitEthernet0/0 interfaces of R1 and R3 as illustrated in the topology. Configure the Loopback interfaces specified in the diagram on R3.
Configuration Steps:
R1(config)#ipv6 unicast-routing R1(config)#interface GigabitEthernet0/0 R1(config-if)#ipv6 address 2001:db8:1::1/64 R1(config-if)#no shutdown R1(config-if)#end R1#copy running-config startup-config R3(config)#ipv6 unicast-routing R3(config)#interface GigabitEthernet0/0 R3(config-if)#ipv6 address autoconfig R3(config-if)#no shutdown R3(config-if)#exit R3(config)#interface lo0 R3(config-if)#ipv6 address 2001:aaaa:aaaa:aaaa::/64 eui-64 R3(config-if)#end R3#copy running-config startup-config
Task 3: Verify Configuration
Objective: Use appropriate show commands to verify IPv6 configurations and interface statuses.
Verification Commands:
R3#show ipv6 interface g0/0 GigabitEthernet0/0 is up, line protocol is up IPv6 is enabled, link-local address is FE80::290:CFF:FE1A:2201 No Virtual link-local address(es): Global unicast address(es): 2001:DB8:1:0:290:CFF:FE1A:2201, subnet is 2001:DB8:1::/64 [CAL/PRE] Joined group address(es): FF02::1 FF02::2 FF02::1:FF1A:2201 MTU is 1500 bytes ICMP error messages [Output Truncated] R3#show ipv6 interface lo0 Loopback0 is up, line protocol is up IPv6 is enabled, link-local address is FE80::2E0:A3FF:FE94:D840 No Virtual link-local address(es): Global unicast address(es): 2001:AAAA:AAAA:AAAA:2E0:A3FF:FE94:D840, subnet is 2001:AAAA:AAAA:AAAA::/64 [EUI] Joined group address(es): FF02::1 FF02::2 FF02::1:FF94:D840 MTU is 1514 bytes [Output Truncated]
