  • Part 2: Configure IPv6 Static and Default Routes
  • Part 3: Verify Connectivity

Background

In this activity, you will configure IPv6 static and default routes. A static route is a route that is entered manually by the network administrator in order to create a route that is reliable and safe. There are four different static routes used in this activity: a recursive static route; a directly attached static route; a fully specified static route; and a default route.

Part 1: Examine the Network and Evaluate the Need for Static Routing

a. Looking at the topology diagram, how many networks are there in total?
5

b. How many networks are directly connected to R1, R2, and R3?
R1 has 2, R2 has 3, and R3 has 2

c. How many static routes are required by each router to reach networks that are not directly connected?
R1 needs to configure 3 static routes, R2 needs to configure 2 static routes, and R3 needs to configure 3 static routes.

d. Which command is used to configure IPv6 static routes?

ipv6 route [network/prefix] [exit interface/next hop address]

Part 2: Configure IPv6 Static and Default Routes

Step 1: Enable IPv6 routing on all routers.

Before configuring static routes, we must configure the router to forward IPv6 packets

Which command accomplishes this?

#ipv6 unicast-routing

Enter this command on each router.

Step 2: Configure recursive static routes on R1.

Configure an IPv6 recursive static route to every network not directly connected to R1

ipv6 route 2001:DB8:1:2::/64 2001:DB8:1:A001::2
ipv6 route 2001:DB8:1:A002::/64 2001:DB8:1:A001::2
ipv6 route 2001:DB8:1:3::/64 2001:DB8:1:A001::2
Step 3: Configure a directly attached and a fully specified static route on R2.

a. Configure a directly attached static route from R2 to the R1 LAN.

ipv6 route 2001:DB8:1:1::/64 Serial0/0/0

b. Configure a fully specific route from R2 to the R3 LAN.


Note: Packet Tracer v6.0.1 only checks for directly attached and recursive static routes. Your instructor may ask to review your configuration of a fully specified IPv6 static route.
#ipv6 route 2001:DB8:1:3::/64 Serial0/0/1 2001:DB8:1:A002::2
Step 4: Configure a default route on R3.

Configure a recursive default route on R3 to reach all networks not directly connected.

ipv6 route ::/0 2001:DB8:1:A002::1
Step 5: Verify static route configurations.

a. Which command is used to verify the IPv6 configuration of a PC from the command prompt?

ipv6config

b. Which command displays the IPv6 addresses configured on a router’s interface?

show ipv6 interface brief

c. Which command displays the contents of the IPv6 routing table?

show ipv6 route

Part 3: Verify Network Connectivity

Every device should now be able to ping every other device. If not, review your static and default route configurations.
