Build a probe-verified dual-ISP failover system on Cisco IOS-XE using IP SLA and Object Tracking. When your primary ISP loses internet connectivity — even if the physical link stays up — automated failover kicks in within seconds without any manual intervention.
Learn how to build and verify an MPLS L3VPN on Cisco IOS-XE from scratch — covering VRF configuration, LDP, MP-BGP VPNv4, PE-CE eBGP routing, and systematic troubleshooting with real CLI output.
A technical deep dive into zero-knowledge proofs — what SNARKs and STARKs are, how they differ, and why they’re now the backbone of blockchain scaling, privacy, and DeFi compliance in 2026.
BGP communities let you tag routes with policy metadata and use that tagging for filtering, traffic engineering, and DDoS mitigation. This guide covers standard, extended, and large communities on Cisco IOS-XE with real CLI examples — from basic send-community config to RTBH blackholing and inbound route tagging by peer type.
Learn how to configure SNMP v3 on Cisco IOS-XE devices with real CLI examples, then feed that data into LibreNMS and Grafana for production-grade network visibility.
Learn how to deploy n8n, the open-source workflow automation platform, on Docker with a PostgreSQL backend, secure it behind a reverse proxy, and build three practical homelab workflows — container health alerts, RSS news digests, and automated backup verification.
Learn how to configure centralized AAA on Cisco IOS-XE using TACACS+ and Cisco ISE 3.3.
A practical engineer’s guide to deploying IPv6 on Cisco IOS-XE: configure global unicast addressing, OSPFv3 routing, dual-stack interfaces, DHCPv6, named ACLs, and NDP — with real CLI output at every step.
I wired up Claude AI routines to act as an autonomous homelab assistant — diagnosing container crashes, monitoring disk usage, checking config drift, and sending plain-English summaries every morning. Here’s the full setup with real Python code.
A complete guide to DMVPN Phase 2 on Cisco IOS-XE: configure mGRE tunnels, IKEv2 IPsec, NHRP registration, OSPF next-hop preservation, and troubleshoot the most common failure modes including NAT traversal and dual-hub redundancy.
A complete, command-by-command walkthrough for upgrading Cisco Catalyst 9300/9400/9500 switches: bundle mode vs. install mode, the install add/activate/commit workflow, ISSU eligibility, common failure scenarios including rommon recovery, post-upgrade verification, and rollback procedures — all with real IOS-XE output.
