  • 1.  Upgrade to to Junos 17 to 20 4R2 on MX 204

    Hi ,
    I work on a new project in IP fabric Span - Leaf architecture VXLAN EVPN-BGP with MX 204 and QFX5120-32C and QFX5120-48Y. I am new on the project and would like to set up a Home lab to practice. What would you suggest? 
    I tried to upgrade my Juniper router MX204 from Junos 17 . Junos 20. 4R2 on MX204 I get ERROR: estimate of space required:4223343 KBYTES available :376580 Kbytes
    I tried to request system storage cleanup and Vmhost cleanup. It won't clean up. I tried to reboot and reinstall still nothing. Do you know another option to push the upgrade? I did show system storage and there is only one file of 4GB. When I reboot the router it still shows the old version. Do you know what else I can do?.

    a. You may try to clean-up files manually, if possible, also if there is some unneeded files in the file system.
    b. For practice, this is easily done in virtual devices, using EVE-NG with the trial images for vQFX and vMX.
