The data network shown below is experiencing a communications failure between the Network A and Network B.
Also, here you can see the routing tables of all the routers: Routing Tables
It is confirmed that all the configuration of the interfaces in the Routers and VPCs is correct and all the WAN links are operational. I have used the PING command from PC-A to PC-D, checking that it is NOT being obtaining a response from the ICMP Echo Request messages that PC-A sends to PC-D and that PC-D must respond with an ICMP Echo Reply message.
So, I need to Identify the name of the router where it is necessary to take action to solve this routing failure.
And also indicate which is the solution and write which is the line or lines of complete command that must be added in that Router in order to solve the routing problem.
Thanks a lot guys!
