Why This Cheat Sheet Matters for ENARSI
This cheat sheet covers the most important EIGRP/OSPF/BGP Redistribution concepts tested on the ENARSI (ENARSI) certification exam. It contains 1 sections with 6 key points that you should memorize before exam day. Use this as a quick-reference guide during your final review sessions.

Redistribution Rules
- Always use route maps to control redistributed routes.
- OSPF external routes: E1 (cost changes with internal metric) vs E2 (fixed cost, default).
- EIGRP external routes get AD of 170 (vs 90 for internal).
- Seed metric is required when redistributing into EIGRP (bandwidth, delay, reliability, load, MTU).
- Use tags to prevent routing loops in mutual redistribution scenarios.
- Distribute lists filter routes in the routing table; route maps offer more granular control.

Cisco Command Quick Reference
Cisco IOS commands follow a hierarchical structure: User EXEC mode (>), Privileged EXEC mode (#), Global Configuration mode (config)#, and Interface Configuration mode (config-if)#. Master the transitions between these modes and the key "show" commands for each technology area — they are heavily tested on every Cisco exam.
