Cisco iou nat overload4/16/2023 ![]() In that scenario the spoke sites would not require default routes out to the “Internet”. The alternative to this is to just connect all the WAN links into a L2 unmanaged switch but then they would be all on one broadcast domain. ![]() I like using a WAN router like this in my topologies because it simulates a real WAN link. So I set the Flat2 portgroup to be on the “VM Network” which is my LAN. ![]() Since I put Flat-2 on my pseudo Wan router in VIRL, I want that to provide internet connectivity. That’s it for the “test” VM it should now be connected to that L2 node via the port group. Now since I put Flat-1 on the switch, this is supposed to be my VM so I’ll set my VM’s port group to “Flat”. The “flat-1” node maps to the “Flat” vswitch port group, and the “flat-2” node maps to the “Flat1” vsiwtch port group. Now how does this connect to our real network? Well through the flat vswitch port groups we had to create when initially installing VIRL from the official guide. Step 1: Drop two “L2 External” nodes onto your topology, I put Flat 1 on my switch, and Flat 2 on my cisco WAN router (for wan connectivity) However at some point in your lab you will find that you want a Server 2012/2016 VM, or you just want some dam network connectivity in this lab. Anyone who talks nerd with me knows I love my subscription to Cisco VIRL.
