Why isn't my basic vlan example working (cbt nuggets) can't tracert and when I do it goes straight to itself from the pc

PC>tracert 10.1.20.50
Tracing route to 10.1.20.50 over a maximum of 30 hops:

You've not configured your router since this looks like a router on a stick exampleGetting There ...

Like xnx, it looks like you need to configure ROAS for your configuration.2017 Certification Goals:

What were the results you were expecting? It looks like it is working from this perspective (proxy-arp).
For you guys suggesting that ROAS is not configured, what should be configured differently? -

What TechGuru80 said, From the information you provide it works like it supposed to do. Also instead of saying PC say PC2 or PC3 and if you could upload the PT file that would help as well. -

this it, but according to CBT Nuggets this is the very basic that i'm trying to replicate, i should be able to do tracert from pc2 to pc3 and it should go through the router, but it is not... -

Tracing to 10.1.20.50 from 10.1.20.50 has no reason to traverse a router. It's the same device.An expert is a man who has made all the mistakes which can be made. -

I am trying to tracert pc 2 to pc3... 10.1.20.50 is not the same as 10.1.10.50, they are not the same device

So is the trace and ipconfig output you pasted above not from the same device? Can you do a traceroute and ipconfig from the same device and post the output? What you have should be enough to get you working. Who knows what works in Packet Tracer though. I've seen way too many people wasting time scratching their heads on something that would work on real IOS.An expert is a man who has made all the mistakes which can be made.

OP - In the above example you show 10.1.20.50 as the ip where you tracert to the same ip?
Also, your config is missing stuff - Configuring InterVLAN Routing and ISL/802.1Q Trunking on a Catalyst 2900XL/3500XL/2950 Switch Using an External Router - Cisco

You don't need a trunk. You can have multiple interfaces two a switch in different VLANs.An expert is a man who has made all the mistakes which can be made.

That is also a layer 3 switch which can accomplish the same thing as ROAS but I am not sure on the limitations of packet tracer or gns3.

according to CBT nuggets on his 1st example, no trunk ports or encapsulation was configured, i understand this is needed for subinterfaces only
