Objectives

Part 1: Propagate an IPv4 Default Route
Part 2: Propagate an IPv6 Default Route
Part 3: Verify Connectivity to Outside Hosts

Scenario
In this activity, you will configure and propagate a default route in EIGRP for IPv4 and IPv6 networks. EIGRP is already configured.

Part 1: Propagate a Default Route in EIGRP for IPv4
Step 1: Verify the EIGRP configuration on each IPv4-enabled
router.

Display the routing table of each IPv4 enabled router and verify that all IPv4 routes are visible we use command
“show ip route”

Step 2: Configure an IPv4 default route.

Configure a directly connected IPv4 default route on IPv4-Edge.

IPv4-Edge(config)#ip route 0.0.0.0 0.0.0.0 s 0/1/0

Step 3: Propagate the default route in EIGRP.

IPv4-Edge(config)#router eigrp 1
IPv4-Edge(config-router)#redistrubute static
IPv4-Edge(config-router)#

Configure the EIGRP routing process to propagate the default route.

Step 4: Verify IPv4 default route is propagating.

Display the routing tables for Branch-1 and Branch-2 to verify the default route is now installed.

Branch-1#show ip route
D*EX 0.0.0.0/0 [170/7289856] via 172.31.6.1, 00:44:21, Serial0/1/0

Branch-2# show ip route
D*EX 0.0.0.0/0 [170/7289856] via 172.31.7.1, 00:49:07, Serial0/0/1

Part 2: Propagate a Default Route in EIGRP for IPv6
Step 1: Verify EIGRP configuration on each IPv6 enabled router.

Display the routing table of each IPv6 enabled router and verify that all IPv6 routes are visible.

IPv6-Edge#show ipv6 route

Step 2: Configure an IPv6 default route.
Configure a directly connected IPv6 default route on IPv6-Edge.

IPv6-Edge(config)#ipv6 route ::/0 serial 0/1/0
IPv6-Edge(config)#

Step 3: Propagate the default route in EIGRP.
Configure the EIGRP routing process to propagate the default route.

IPv6-Edge#config t
IPv6-Edge(config)# ipv6 router eigrp 1
IPv6-Edge(config-rtr)# redistribute static

Step 4: Verify IPv6 default route is propagating.

Display the routing tables for Branch-3 and Branch-4 to verify the default route is now installed.

  • For Branch-3
    Branch-3#show ipv6 route
    EX ::/0 [170/7289856] via FE80::1, Serial0/0/0
  • For Branch-4
    Branch-4#show ipv6 route
    EX ::/0 [170/7289856] via FE80::1, Serial0/0/1

Part 3: Verify Connectivity to Outside Hosts
· PC1 and PC2 should now be able to ping IPv4 Outside Host.


· PC3 and PC4 should now be able to ping IPv6 Outside Host.
