- As JUNOS runs on NetBSD, we need to create a base image which has NetBSD and JUNOS installed on them. We can use this base image as Junos image file in GNS.
- Detailed steps are given on above links. Download Free NetBSD, patched qemu for windows, TAP interface (from ‘Open VPN’).
- Create a base image with NetBSD using qemu and partition the OS to accommodate Junos image install on them. Allocate space for root, config, swap region.
- Install TAP interface to establish communication between PC and the ‘base image’ to download Junos to base image.
- After downloading Junos to base image, add this package to netbsd. After installing, compress the image file using qemu to save some memory space.
- Use the above image in GNS as ‘Junos image’. Check whether the paths given to qemu, qemu-img and qemu-wrapper in GNS are correct and test it.
- Manually add an interface between Juniper router to another juniper/cisco router and run the topology.
