I have a network designed in the image given below which is configured with RIPv2. I need to connect this network to the internet in simulation. How to simulate internet in cisco packet tracer? Thanks.

- For your simulation, you could just put another router in between the two site routers to act as the Internet.
- The commented routes will allow you to get the the Internet
interface of the other side. I'm puzzled by the different masks used
in the routes. You have
255.255.255.248assigned to the interfaces, and you use that on the router at the Main site, but at the Remote site you use255.255.255.255as the route to the Main router. Neither one will allow general Internet access since you have your default route pointing to your LAN at the Main site. You may want to adjust the default route at the Remote site to point to the next hop (T1) and add another default route with a higher AD to point to the VPN to give you a backup default route for when the T1 fails.
As you said, that command does not exist on packet tracer. The only command I can suggest to you would be "show ip interface brief" which will not show you the speeds though. This is mainly used to display ip addresses assigned to layer 3 ports. Alternatively, you just need to use "show interface" and view all the details of the port. But with "show ip interface brief", it will at least show you the status. – SleepyMan
Packet Tracer does not support this command yet. (v7.1.1).
Packet Tracer is a simulator and it comes with some limitations. It does not run all commands that run in real Switches or Routers.
GNS3 is an alternative to Packet Tracer and it supports this commands.

What is GNS3?
GNS3 allows you to visualize, plan, test and troubleshoot network environments across any vendor platform at scale - without the need to directly interact with the network hardware. With the intuitive graphical interface, users can seamlessly connect all types of virtual interfaces to compose a real representation of networks. GNS3 runs on traditional PC hardware and may be used on multiple operating systems, including Windows, Linux, and MacOS X.
What is the difference between an emulator and a simulator?
An emulator will run an exact copy of an actual network operating system. A simulator is designed to have a resemblance to the actual network operating system, but only 'simulate' functions. GNS3 Ironically has 'simulator' in its acronym, but it simulates entire networks, not just network operating systems. Most users use GNS3 to emulate Cisco IOS as well as other vendors. But what sets GNS3 apart from other simulators, is its ability to EMULATE routing and switching as well as incorporate REAL virtual machines and connect them together via a logical tunneling system (overlay network). That is why it is better to say where other software SIMULATE, GNS3 has made advances to EMULATE your real production networks.
What is the difference between GNS3 and Packet Tracer / VIRL?
Packet Tracer and VIRL are Cisco's offerings and answers to the advancement of GNS3's advanced EMULATION. There are strengths and weaknesses to each product, but GNS3 is first in Emulating real production networks. For more information attached are some recent articles written on the comparison: Cisco VIRL vs. GNS3 - How They Compare - GlobalConfig.net (Un)Biased review of someone who used VIRL

Previously in packet tracer I have setup an additional router simulating google dns as the IP address (8.8.8.8) to act as the internet based location. This has helped as a simple simulation allowing test ACL's and routing.
