Lab 7 Troubleshooting Static Routing

Objective
To troubleshoot using ping and tracert.

Topology

Basic Setting

IPs for PCs and routers and static routes have been configured.

PC4 can ping PC5.
PC4 can ping PC1.

PC4 pings PC0, request timeout.
PC4 pings PC2, request timeout.
PC2 ping PC4:
PC>ping 172.16.22.24

Pinging 172.16.22.24 with 32 bytes of data:

Reply from 192.168.0.1: Destination host unreachable.
Reply from 192.168.0.1: Destination host unreachable.
Reply from 192.168.0.1: Destination host unreachable.
Reply from 192.168.0.1: Destination host unreachable.

Ping statistics for 172.16.22.24:

Requirements

To pinpoint the router with incorrect settings.
Steps

Based on thes outputs, settings on Router0 should be checked.
So

Router#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
172.16.0.0/24 is subnetted, 7 subnets
S 172.16.0.0 [1/0] via 172.16.3.1
S 172.16.1.0 [1/0] via 172.16.4.1
S 172.16.2.0 [1/0] via 172.16.5.2
C 172.16.3.0 is directly connected, Serial2/0
C 172.16.4.0 is directly connected, Serial3/0
C 172.16.5.0 is directly connected, Serial6/0
S 172.16.6.0 [1/0] via 172.16.3.1
S 192.168.1.0/24 [1/0] via 172.16.3.1

No route to 192.168.0.0 255.255.255.0 is found.
