Hi everyone, i'm having a problem with a network in my simulator, i have network with a router making 2 subnets, every subnet have a switch. The problem is i cannot ping from a pc to the router, doesn't reach the router, only the switch.
The simulator says that there's "No communication protocol is presente for router 2600.A protocol needs to be present that allows communication to take place. You need either default/static routes established, RIP running, or IGRP running."
The router active configuration (my subnets are in the FastEthernet ports)(Cisco 2600) :
Router(config)#show running-config
^
% Invalid input detected at '^' marker.
Router(config)#exit
Router#show running-config

You have not given us any detail to work with to understand your situation and to identify your problem. I will make these suggestions but having better information about how the switch is set up would allow us to give you better answers,
- is this a layer 2 switch or a layer 3 switch?
- are you pinging from the switch itself or from a PC connected to a switch port/interface?
- if from the switch do you have a valid IP address configured on the management interface of the switch? does the switch have a valid default gateway configured?
- if from a PC do you have a valid IP address and mask configured on the PC? Is the default gateway configured on the PC and is it working?
- are you trying to ping something in your own subnet or is the destination in a remote subnet?
If you can clarify these things then perhaps we can find answers to your issue.

The only way it would work right now is to have a single connection from the router to the switch from router interface F0/0 which is the subnet that the switch ip address is in .What ip address does your client have ? It would have to have a 10.87.200.x address if they are on the switch. Where do the switches hook to the router ? It also looks like everything on the switch is in vlan 1 so no other subnets would work . What you would have to do if you need to have multiple subnets would be to setup trunking on the router with subinterfaces and run a single link to the switch . You then would have to create vlans on the switch itself if you need more than 1 subnet on that same switch.
this might help with the trunking end .
