The challenge
A growing company was opening offices across India and needed a secure, standard network in each city, connected to headquarters, the data centers and its AWS VPCs – with failover when a link went down.
What I did
- Led the deployments of Juniper SRX firewalls and EX switches in Bangalore, Delhi, Pune, Chennai and Hyderabad.
- Built site-to-site IPsec and SSL VPNs, NAT and URL filtering on Juniper SRX and Sophos.
- Designed OSPF routing with failover paths between the branches and HQ.
- Ran a proof of concept for IPv6 to check standards and application compatibility.
- Documented SOPs and topology diagrams for operations and audits; led L3 escalations 24/7.
Outcome
- A standard, secure branch design repeated in five cities.
- Automatic failover between branches and HQ.
- Audit-ready documentation and a tested path towards IPv6.
