Ping through 2800 series Router

[Brian AD]

I run a networking lab at a University.  We are introducing routers, IP subnetting, and routing this week.  There are two switches connected to a single router (FE0/0 and FE0/1, respectively).  I am attaching the workstation IP address configs, and router show ip interface brief and show ip route outputs.  The workstations can ping their local router port (default gateway), the remote router port, but not any devices beyond the remote router port.  There are no ACLs established.  I believe there is something simple I am missing, but cannot put my finger on it.

Thank you,

Brian

Additional information:  When running tracert across the subnets, there is a response from the local router port, but no response from the remote router port.

Hello @Brian AD ,

check windows firewall on the PCs your configuration looks like good and local subnet can be pinged from both

Hope to help

Because our lab environment is air-gapped, I have Windows firewall turned off.

Enable ip routing in global configuration mode with the command ip routing

[Brian AD]

No change.

Hello @liviu.gheorghe ,

I had thought about this point too. But the output the OP provided looks that of a router with ip routing enabled there is a line gateway of last resort not set. if ip routing is disabled show ip route should show only the IP default gateway.

Hope to help

Hello @Giuseppe Larosa , thank you for pointing that out - you are right.

Should be something in the switch configuration.

@Brian AD , can you share the switch configs with us?

[Brian AD]

Attached running-config files for both the switch and the router.

PC1-SW1-R-SW2-PC2

PC1 and PC2 must config with GW point to R interface.

SW must config with access not trunk port.

No, physical hardware.

[Brian AD]

I have removed all VLAN information (except default VLAN1), including IP Addresses.  Still not working.

[Brian AD]

Would any kind of security setting cause this?  I did enable SSH and telnet access (so had to create an RSA key), but it does not seem like that should influence basic routing.

[liviu.gheorghe]

More likely the connectivity issue is due to some VLAN or trunking configuration in the switches attached to the router ports.

A look at the switches configurations will clarify this.
