Asking for help

[xgabin63]

Hello everyone,

I am a beginner to networking courses and I would like to ask if anyone can help me to found where I made a mistake on the below simple configuration. I can't ping one PC to another. I crosschecked but I am not seeing where is the mistake.

Thank you in advance for your assistance.

Regards,

Gabin

Post full configuration of all devices - with this high level we can not assume what configured on  switch config and router full config.

basic test :  PC1 can able to ping Gateway of Router ? PC2 same case and PC3 same case ?

Hello,

From this picture and part of code we can't conclude anything about your R1 routing table. It would be helpful if you posted full example (in Packet Tracer, e.g.) or screenshot of how R1 routing table is configured for starters.

Best wishes!

You can attach your PT file here but it must be in a zip format.

Basic TS steps:

Can PC ping its default gateway (router)? Is PC on the same network (subnet) with its default gateway.?

can PC ping other interface IP on default gateway router?

Are PC and Router on the same vlan x ?

are they on access vlan port (trunk in some cases)?

Is vlan x present in the vlan database on switch.

is there port security on switch?

Hello,

if this is a Packet Tracer project, which router did you use (as there is no router with three GigabiEthernet interfaces, at least not by default) ?

Either way, I pieced together a project using the information you posted, with full connectivity. Review the router config and compare that with yours.

I have saved the project in PT version 7.3.1., so you need that to open the file.
