Module 3 Summary and Common Pitfalls
→
Longest prefix match is checked before administrative distance, and AD is checked before metric — memorize this order specifically, since it's a frequently tested and frequently misunderstood sequence.
→
OSPF's network command uses a wildcard mask, not a subnet mask — inverting this is an extremely common configuration mistake.
→
A DR/BDR election only happens on multi-access segments; on point-to-point links between exactly two routers, there's no DR/BDR, and neighbor state reaching FULL directly is expected and normal.
→
Remember HSRP's core value proposition: it's transparent to end hosts — they never reconfigure anything, even during a failover event.
→
Static routes without dynamic protocols don't adapt to topology changes — know when a scenario calls for static (small, stable network) versus OSPF (larger or more dynamic topology).
