CCNA LAB25: Configuring IPv6 Default Routes

小乔

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
R1(config-if)#end
R1#

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

R1#show ipv6 route
