Little help with Packet Tracer

[Kyle Ar]

I am trying for the life of me to figure out what I am doing wrong.

The PT activity page says the following.
Default routes (on R3)
-Create an IPv4 default route on R3 using GI0/1 as an exit interface

Here is the command I am putting in
ip route 209.165.200.0 255.255.255.0 gigabitEthernet 0/1

This is the error it spits back at me.
%Default route without gateway, if not a point-to-point interface, may impact performance

The IPv4 address of gigabitEthernet 0/1 is 209.165.200.1/24

Here is a link to the Packet Tracer file if anyone could help me.

Thank you very much

First read the instructions!!!!!

It says to create a default route.

The message you receive is bacause an Ethernet interface is not a point-to-point interface.

Think back to the very basics of how ethernet works i.e. the MAC address of the destination must be known before the frame is transmitted.

I'll make it more clear.

A route determines where traffic is sent. To be effective, the route needs to know what the next-hop is, where it can send the packets in the upstream direction (to the Internet). On a point-to-point interface, there are only 2 routers connected. Your router and 1 other router. So if you configure a route over a p2p interface, you don't need to specify the next-hop. If you send a packet out over the p2p interface, it will arrive at the correct next-hop anyway.

On a multi-point interface, it's different. Specifying "I want to send all traffic out over Ethernet0" does not contain enough information. You need to specify to which ip-address exactly you need to send traffic to. In other words: you need to specify the next-hop ip-address.

Is 209.165.200.1/24 the ip-address on your own router ?
If so, try to figure out what the ip-address on the upstream router is. It must begin with 209.165. 200. Maybe something like 209.165.200.254 ? Or 209.165.200.2 ? You need to know this.

Also, what you are configuring is not a default route. A default route is always to 0/0 (prefix-notation), or 0.0.0.0/0.0.0.0 (ip-address/ip-mask notation).

Then configure "ip route 0.0.0.0 0.0.0.0 209.165.200.254".

It might be that you are actually trying to do something else. No idea. But that is the way to configure a default route. Hope it helps.

Clearly he was looking for help with his homework, and is enrolled in a college/community college course, probably the second course toward CCNA.

At that point, there should not be a need to explain all the details regarding what a "default route" is, its purpose, etc.. As for the message (which is NOT an error message, as he assumed) he received when configuring an exit interface route statement on a multi-access interface, that should not be a mystery. These are basic concepts that should have down cold from the first course toward a certification.

And not even a thanks from the OP for help on his homework.
