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.
