Emulating Cisco IOS, IOSXR, and NXOS

[renji]

Looking for an emulator that can handle all these facets in order to migrate our typology and configs over for testing, mapping, and referencing. Something similar to packet tracer, while being able to support XR and NX platforms. Any suggestions are helpful.

You can use cisco CML 2.5 ( 200$ paid version)

other free version i use was PNET Lab (google it) or eve

Note: all that images required good computing and RAM to run as expected ( you may not 100% emulate like physical, you can find some limitations due to virtual)
