BGP policy and path selection
eBGP underlay design, import/export policy, communities and failure behaviour.
Technical notes
Engineering notes, distilled.
A growing knowledge base for the concepts, commands and design decisions behind the lab — concise, practical reference material rather than copied documentation.
EVPN / VXLAN
VTEPs, VNIs, route targets, MAC learning and the transition toward routed tenant services.
Junos routing & switching
Structured concepts, scenarios and CLI validation for enterprise Junos environments.
SRX segmentation
Zones, security policy, NAT, reachability intent and test methodology.
802.1X troubleshooting
Authentication flow, switch/ISE integration and the checks that narrow down common failure modes.
ZTP at scale
How zero-touch deployment fits into a real access-switch refresh rather than a perfect greenfield lab.
