Use of loopback or ethernet ports for testing in home lab...
After moving, I've set back up my home lab in order to study for my CCNP switch test.
I used to use multiple computers plugged into ports on various switches/routers for my end-to-end ping test.
However, due to power, I'm having to come up with other ways of performing end-to-end test. I've started setting up loopbacks but remember something from my ccna days about turning on an ethernet port (even though nothing was plugged into it) so that it appears to be in an up/up state.
What do you use to simulate end-point devices? Any secrets you care to share?
Thank you so very kindly for your time and suggestions.
Your friend,

Personally, I use loopbacks, 'no keepalive', VPCS for basic connectivity and virtual hosts of vmware & virtualbox.
The choice dependent on what I plan to do with the host.
I take from this thread, I should be able to emulate hosts (for end-to-end) using a switch or an loopback address on a router.....I'm apparently slow on the uptake. Would someone be gracious enough to help me configure this? I understand loop back and vlan but I can't get my brain to get it as it applies here or how to set it up.
I have a lab set up and plenty of hardware to use but missing something fundamental.
Thanks.

interface loopback10
ip address 10.0.0.1 255.255.255.0

interface loopback 10
ip address 10.1.0.1 255.255.255.0
Now you can just ping sourcing these interface addresses to test end to end connectivity.
ping 10.1.0.1 source 10.0.0.1
Wow, thank you. Seeing it stated like you did makes perfect sense, I was WAY over complicating the issue needlessly. Simple and elegant....I really have to stop over thinking things, it's a damnable character trait.
The only other question I have about this; Can I do this with sub-interfaces as well?
Thanks very much for the light, I appreciate it!
