VMware NSX-T and Juniper dynamic routing via BGP
After few NSX (NSX-V) designing & deploying projects,
I installed NSX-T at my lab, it was harder then i thought 🙂
It’s very different from NSX-V.
This is my NSX-T lab physical topology

Important tips for installing CiscoWorks 3.2
First get your copy of ciscoworks 3.2 from-
Before installing
- Set computer name
- Set IP addresses and make sure Interface is UP !
- Check that you can ping your computer name
- Make sure that your computer name resolved to your Interface IP (Not 127.0.0.1),
If you change it later you will have a lot of problems..
- Data restore allowed only from the same CiscoWorks version (It’s Not possible to restore a backup from LMS 3.2 to LMS 3.2.1)
