A network engineer runs the following command to verify BFD operation:
R1# show bfd neighbors detail
IPv4 Sessions NeighAddr LD/RD RH/RS State Int
10.1.1.2 1/2 Up Up Gi0/0
Session state is UP and not using echo function. Session type: single-hop Local Diag: 0, Demand mode: 0, Poll bit: 0 MinTxInt: 1000000, MinRxInt: 1000000, Multiplier: 3 Received MinRxInt: 1000000, Received Multiplier: 3 Holddown (hits): 0 (0), Hello (hits): 1000/5 Rx Count: 1000, Rx Interval (ms) min/max/avg: 900/1100/1000 Tx Count: 1000, Tx Interval (ms) min/max/avg: 900/1100/1000
What does this output indicate?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
BFD session is operating with async mode, intervals at 1 second.
The output shows a BFD session in UP state with consistent transmit and receive intervals around 1000 ms, no echo function, and a multiplier of 3. The session is healthy.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
BFD session is using echo mode for fast failure detection.
Why it's wrong here
The output explicitly states 'not using echo function'.
- ✗
BFD session is down and not sending hellos.
Why it's wrong here
State is UP and hello counts are incrementing.
- ✓
BFD session is operating with async mode, intervals at 1 second.
Why this is correct
MinTxInt and MinRxInt are 1,000,000 microseconds (1 second), no echo, and session is UP.
- ✗
BFD session has a holddown timer of 3 seconds.
Why it's wrong here
Holddown is 0; the multiplier is 3, but holddown hits are 0.
