Destination Host Unreachable

[EdwinGoodridge1872]

Hi,

my name is Edwin

I'm a student and I'm working on the this assignment and I'm having trouble with it

I trying to ping PC5 from PC0, but it keep saying Destination Host Unreachable. Can someone take a look and give some solution?  

Thank you

Hi @EdwinGoodridge1872 ,

The routers must have a route marked for all the networks of your topology.
You can achieve this with the RIPv2 protocol:

Router0

Router(config)#router rip

Router(config-router)#version 2

Router(config-router)#no auto-summary

Router(config-router)#network 192.168.43.0

Router(config-router)#network 192.168.43.16

Router(config-router)#network 192.168.43.32

Router1

Router(config)#router rip

Router(config-router)#version 2

Router(config-router)#no auto-summary

Router(config-router)#network 192.168.43.4

Router(config-router)#network 192.168.43.48

Router(config-router)#network 192.168.43.64

Router2

Router(config-router)#router rip

Router(config-router)#version 2

Router(config-router)#no auto-summary

Router(config-router)#network 192.168.43.8

Router(config-router)#network 192.168.43.80

Router(config-router)#network 192.168.43.96

Router3

Router(config)#router rip

Router(config-router)#version 2

Router(config-router)#no auto-summary

Router(config-router)#network 192.168.43.0

Router(config-router)#network 192.168.43.4

Router(config-router)#network 192.168.43.8

After those configurations, the ping will be successful.
Remember to mark the correct answers as solved, since that helps other users with similar doubts.

Hi @EdwinGoodridge1872 ,

Another way to achieve connectivity can be through static routes:

Router0

ip route 192.168.43.48 255.255.255.240 FastEthernet4/0

ip route 192.168.43.64 255.255.255.240 FastEthernet4/0

ip route 192.168.43.80 255.255.255.240 FastEthernet4/0

ip route 192.168.43.96 255.255.255.240 FastEthernet4/0

Router1

ip route 192.168.43.80 255.255.255.240 FastEthernet4/0

ip route 192.168.43.96 255.255.255.240 FastEthernet4/0

ip route 192.168.43.16 255.255.255.240 FastEthernet4/0

ip route 192.168.43.32 255.255.255.240 FastEthernet4/0

Router2

ip route 192.168.43.16 255.255.255.240 FastEthernet4/0

ip route 192.168.43.32 255.255.255.240 FastEthernet4/0

ip route 192.168.43.48 255.255.255.240 FastEthernet4/0

ip route 192.168.43.64 255.255.255.240 FastEthernet4/0

Router3

ip route 192.168.43.16 255.255.255.240 FastEthernet4/0

ip route 192.168.43.32 255.255.255.240 FastEthernet4/0

ip route 192.168.43.48 255.255.255.240 FastEthernet5/0

ip route 192.168.43.64 255.255.255.240 FastEthernet5/0

ip route 192.168.43.80 255.255.255.240 FastEthernet6/0

ip route 192.168.43.96 255.255.255.240 FastEthernet6/0

After those configurations, the ping will be successful.
