Install gns3 2.1 on windows 10 by configuring the gns3 gui and vm with a suitable hypervisor. You must supply your own device operating system images, such as Cisco IOS.
Learn to download and install the GNS3 GUI for Windows, meet minimum and recommended system requirements, and complete the setup wizard with default options.
Configure a GRE tunnel between two customer routers, assign IP addresses (DHCP or static), observe encapsulation, and enable ibgp across the tunnel to exchange routes.
Understand how IPsec tunnels encrypt traffic and protect sensitive data, as Wireshark shows cleartext ICMP between endpoints versus encrypted ESP payload between routers.
Configure a full-mesh dmvpn with static and dynamic tunnels using bgp across hub and spoke sites, testing connectivity with ping and dmvpn outputs; plan nat for ubuntu clients.
Configure for DMVPN: set up BGP, GRE, and IPsec across multiple customers, establish tunnel and crypto peer relationships, and verify encrypted connectivity via ping tests.
Configure dynamic IPsec VPNs between two Cisco routers using a VPN config generator, handling dynamic IP addresses on both sides, NAT, IPsec, pre-shared keys, and ping-based testing for encryption.
Learn how to configure multiples Cisco VPNs using GNS3.
Download the GNS3 labs and try yourself! Or watch me configure the VPNs.
You will get downloadable GNS3 portable project files which you can import into GNS3.
Learn how to practically configure Cisco VPNs including:
- GRE
- IPsec
- DMVPN
and more!
Ask yourself these questions:
- Are you ready and prepared for the VPN labs in the CCNA, CCNP or CCIE exams?
- Are you able to troubleshoot Cisco networks?
Answer:
This course helps you prepare for the exam and gain the confidence to pass the exam!
There are many topologies and many labs in this course!
Requirements: This course uses Cisco IOS images from Cisco VIRL and GNS3. To be able to complete the labs, you will either need physical equipment or virtual IOS images. For example: Cisco VIRL IOSv and IOSvL2 images; or physical routers and switches.
