Verify that the routes are no longer in the routing table.
Step 4.
R3#
show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter
area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
172.16.0.0/22 is subnetted, 1 subnets
S 172.16.0.0 [1/0] via 192.168.1.2
C 192.168.1.0/24 is directly connected, Serial0/0/1
C 192.168.2.0/24 is directly connected, FastEthernet0/0
R3 now only has one route to any host belonging to networks 172.16.0.0/24,
172.16.1.0/24, 172.16.2.0/24, and 172.16.3.0/24. Traffic destined for these networks will
be sent to R2 at 192.168.1.2.
Use
ping
to check connectivity between the host PC3 and PC1.
Step 5.
From the host PC3, is it possible to ping the host PC1?
yes
This ping should be successful this time because there is a route to the 172.16.3.0 network
on the R3 router, and the R1 router can return the packet using the default route.
Task 12: Summary, Reflection, and Documentation
With the completion of this lab, you have
Configured your first network with a combination of static and default routing to provide full
connectivity to all networks
■
Observed how a route is installed in the routing table when you correctly configure and activate
an interface
■
Learned how to statically configure routes to destinations that are not directly connected
■
Learned how to configure a default route that is used to forward packets to unknown destinations
■
Learned how to summarize a group of networks into one static route to reduce the size of a
routing table
