Does anyone out there have experience setting up loopback addresses on routers and being able to ping from other devices in the configured senario? These are all physical devices that I have.ĬAN ping from each router to the loopback of the switch (without even a static route in either router pointing to the loopback's next hop from the router to the switch). I need to get back to my studying and this is taking a very long time. I am at a point in my studying where I need to be able to ping loopback interfaces on different routers. Below I have several updates, things I have tried.
