Lab 25: Configuring IPv6 Default Routes

Lab Objective:

The objective of this lab exercise is for you to learn and understand how to manually configure static default IPv6 routes.

Lab Purpose:

Manually configure IPv6 interface addressing, and then configure a static default route so R1 can reach the addresses on the Loopbacks of R2.

Certification Level:

This lab is suitable for CCENT certification exam preparation.

Lab Difficulty:

This lab has a difficulty rating of 7/10.

Readiness Assessment:

When you are ready for your certification exam, you should complete this lab in no more than 10 minutes.

Lab Topology:

Please use the following topology to complete this lab exercise:

Task 1:

Configure the hostnames on routers R1 and R2 as illustrated in the topology.

Task 2:

Configure the IPv6 addresses on the FastEthernet interfaces of R1 and R2 as illustrated in the topology. Add the Loopback addresses to R2.

Task 3:

Configure a default static route on R1 to allow traffic to reach the subnets connected to R2.

Task 4:

Ping across the link, and then use relevant show commands to verify your configuration.

Configuration and Verification

Task 1:

For reference information on configuring hostnames, please refer to earlier labs.

Task 2:

R1(config)#ipv6 unicast-routing 
R1(config)#int f0/0 
R1(config-if)#ipv6 add 3fff:1234:abcd:1::1/64 

R2(config)#ipv6 unicast-routing 
R2(config)#int f0/0 
R2(config-if)#ipv6 add 3fff:1234:abcd:1::2/64 
R2(config-if)#no shut 
R2(config-if)#interface Loopback0 
R2(config-if)#ipv6 address 3FFF:1234:AAAA:1::1/64 
R2(config-if)#interface Loopback1 
R2(config-if)#ipv6 address 3FFF:1234:BBBB:1::1/64 

R2#show ipv6 int f0/0 
FastEthernet0/0 is up, line protocol is up   
 IPv6 is enabled, link-local address is FE80::C001:8FF:FE52:0 
  No Virtual link-local address(es): 
  Global unicast address(es): 
   3FFF:1234:ABCD:1::2, subnet is 3FFF:1234:ABCD:1::/64

Task 3:

R1(config)#ipv6 route ::/0 f0/0 FE80::C001:8FF:FE52:0

Task 4:

R1#ping ipv6 3fff:1234:aaaa:1::1

Type escape sequence to abort. 
Sending 5, 100-byte ICMP Echos to 3FFF:1234:AAAA:1::1, timeout is 2 seconds: 
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/19/24 ms 

R1#ping ipv6 3fff:1234:bbbb:1::1 

Type escape sequence to abort. 
Sending 5, 100-byte ICMP Echos to 3FFF:1234:BBBB:1::1, timeout is 2 seconds: 
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/20/24 ms
