CCNP Daily Drill: Dual-point redistribution loops
Can you stop mutual redistribution loops using route tags? Drop your answer in the comments before the timer runs out.
The question
Two routers mutually redistribute OSPF and BGP. How do route tags stop routing loops?
The answer
A Filter tagged routes from re-entering
You tag routes on injection, then deny that tag on the second router so they can't loop back. Don't rely on AD tweaks alone here. Follow for tomorrow's rep.
Exam tip
Read what the question is actually asking before looking at the options. The wrong answers here are ones candidates genuinely pick — each is true of something adjacent, just not of what was asked.
