Juniper Virtual Production Network

Key Technologies:

  • GNS-3 2.2.51 Network Topology Emulator
  • Juniper vJunos-switch 23.2R1.14
  • Juniper vSRX 20.4R1 3.0 Next Generation Firewall
  • Rapid Spanning-tree protocol
  • Link-Aggregation control protocol
  • Network Address Translation
  • DHCP over Layer 3 LACP
  • Juniper J-web management platform

Accomplishments:

  • Familiarized myself with the Juniper OS command structure to ensure consistent setup and deployment of Juniper OS based devices and protocols across a range of devices.
  • Deployed and configured Juniper vSRX 20.4 NGFW as a gateway to both serve and secure internal network infrastructure.
  • Implemented Link-aggregation to ensure consistent layer 2/3 connectivity across both control and data-planes.
  • Arranged redundant switch forwarding using Rapid spanning tree protocol to ensure consistent and secure connection to endpoint devices
  • Established secure endpoint links using port-fast and BPDU blocking on edge ports to ensure the stability of layer two operations.
  • Deployed and tested several endpoint devices and ensured the stability of redundant links through intentional disconnection of lines leading to default gateway.

Additional Improvements added 11-14-2024:

  • Added High-Availability Network Uplink by configuring VRRP across two Identically configured vSRX Firewalls serving as gateways for the Network below them.
  • Added two additional vEX switches acting as a core layer and configured RSTP across redundant links providing a stable and redundant connection from the access layer up to the gateway.
  • Configured SFTP to allow configuration redundancy across VRRP connected routers.
