Quick Answer
The answer is 30 seconds. This default update timer value is defined in RFC 1058, which specifies that RIP sends its entire routing table to neighboring routers every 30 seconds to maintain network convergence. In a VRF-Lite setup, this timer remains unchanged because RIP operates independently within each VRF instance, meaning the 30-second update interval applies per VRF routing table, not globally. On the Cisco CCNP ENARSI 300-410 exam, this concept tests your understanding that VRF-Lite does not alter fundamental RIP timers; a common trap is assuming that VRFs modify protocol defaults or that the update timer differs in a multi-VRF environment. Remember, RIP’s 30-second update is a fixed standard—think of it as the “half-minute heartbeat” for route propagation, regardless of VRF boundaries.
This 300-410 practice question tests your understanding of vrf-lite. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
In a VRF-Lite setup using RIP, what is the default update timer value?
30 seconds
RIP uses a default update timer of 30 seconds.
60 seconds
Why wrong: This is the default holddown timer for RIP, not the update timer.
90 seconds
Why wrong: This is the default flush timer for RIP.
180 seconds
Why wrong: This is the default invalid timer for RIP.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
30 seconds
RIP sends routing updates every 30 seconds by default, as defined in RFC 1058.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
30 seconds
Why this is correct
RIP uses a default update timer of 30 seconds.
Related concept

60 seconds
Why it's wrong here
This is the default holddown timer for RIP, not the update timer.
90 seconds
Why it's wrong here
This is the default flush timer for RIP.
180 seconds
Why it's wrong here
This is the default invalid timer for RIP.
Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
