A network engineer runs the following command on Router R1:
R1# show bfd neighbors detail
IPv4 Sessions NeighborAddr LD/RD Int State Holdown(mult) Intf
10.1.1.2 1/3 Gi0/0 Up 3000(3) Gi0/0
Session state is UP and not using echo function. OurAddr: 10.1.1.1 Handle: 1 Local Diag: 0, Demand mode: 0, Poll bit: 0 MinTxInt: 1000000, MinRxInt: 1000000, Multiplier: 3 Received MinRxInt: 1000000, Received Multiplier: 3 Holddown (hits): 3000(0) Rx Count: 100, Tx Count: 100
Based on this output, what is the BFD session's local discriminator?

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The local discriminator is 1.
Why this is correct
The LD (Local Discriminator) is 1 as shown in the output.
- ✗
The local discriminator is 3.
Why it's wrong here
3 is the remote discriminator (RD).
- ✗
The local discriminator is 10.1.1.1.
Why it's wrong here
This is the local IP address, not the discriminator.
- ✗
The local discriminator is 10.1.1.2.
Why it's wrong here
This is the neighbor IP address, not the discriminator.
