Lab 24: Configuring IPv6 Static Routes

Lab Objective:

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

Lab Purpose:

Manually configure IPv6 interface addressing, and then configure static routes 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. Ping from R1 to R2. Also, using the relevant show commands, find the link-local IPv6 address and ping that.

Task 3:

Configure two static routes on R1 to allow traffic to reach the subnets connected to R2.

Task 4:

Ping across the link, and then use the 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)#no shut 
R1(config-if)#end 
R1#show ipv6 interface brief 
FastEthernet0/0            [up/up] 
  FE80::C000:6FF:FEEC:0 
  3FFF:1234:ABCD:1::1 

R2(config)#ipv6 unicast-routing 
R2(config)#int f0/0 
R2(config-if)#ipv6 add 3fff:1234:abcd:1::3/64 
R2(config-if)#no shut 

R2#ping ipv6 3fff:1234:abcd:1::1 

Type escape sequence to abort. 
Sending 5, 100-byte ICMP Echos to 3FFF:1234:ABCD:1::1, timeout is 2 seconds: 
!!!!! 
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/23/44 ms 

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::3, subnet is 3FFF:1234:ABCD:1::/64
[Output Truncated]

Note: Because link-local IPv6 addresses are not held in the routing table, you need to specify an exit interface when issuing a ping.

R1#ping ipv6 FE80::C001:8FF:FE52:0 
Output Interface: f0/0 
% Invalid interface. Use full interface name without spaces (e.g. Serial0/1) 
Output Interface: fastethernet0/0 
Type escape sequence to abort. 
Sending 5, 100-byte ICMP Echos to FE80::C001:8FF:FE52:0, timeout is 2 seconds: 
Packet sent with a source address of FE80::C000:8FF:FE52:0 
!!!!! 
Success rate is 100 percent (5/5), round-trip min/avg/max = 16/21/40 ms 

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

Task 3:

R1(config)#ipv6 route 3FFF:1234:AAAA:1::/64 FastEthernet0/0 FE80::C001:8FF:FE52:0
 R1(config)#ipv6 route 3FFF:1234:BBBB:1::/64 FastEthernet0/0 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:
