OSPF and EIGRP
EIGRP Stubs in Modern Hybrids
Stub positioning, query boundary behavior, and coexistence patterns when OSPF and EIGRP share administrative boundaries.
Overview
Short labs isolate query propagation, followed by integration scenarios where you document redistribution guardrails. Expect blunt feedback on vague diagrams.
What is included
- Query boundary lab pack
- Redistribution guardrail checklist
- Mentor markup of two topology drawings
- Comparison matrix: stub vs leak-map cases
- Troubleshooting voice note prompts
- Optional reading on metric compatibility
- Capstone presentation to peer panel
Outcomes
- Predict query behavior before enabling stubs
- Choose leak-map vs component routes with rationale
- Explain hybrid designs to a security reviewer

FAQ
Is DMVPN covered?
Only where tunnel interfaces interact with EIGRP adjacencies; full DMVPN design is not included.
Do I need physical gear?
No. Labs run on the provided VM; optional rack tokens are limited.
What if I only use OSPF today?
You can attend, but expect extra study time on EIGRP fundamentals before week two.
Participant notes
“EIGRP Stubs in Modern Hybrids finally clarified why our query storms happened at the DC boundary—not magic, just boundaries we never drew.”
