300-410 Practice Question: Runs the following command on Router R1: R1# show…
A network engineer runs the following command on Router R1:
R1# show bgp ipv4 unicast summary
BGP router identifier 192.168.0.1, local AS number 65001 BGP table version is 10, main routing table version 10
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd 192.168.1.2 4 65002 1002 1000 10 0 0 00:15:30 5 192.168.2.2 4 65003 1005 1003 10 0 0 00:14:20 3 10.10.10.2 4 65004 0 0 0 0 0 00:00:05 Idle
Based on this output, what is the problem with neighbor 10.10.10.2?
⚠ Common exam trap
Cisco often tests the distinction between Idle (no session attempt) and Active (session attempt in progress), tricking candidates into thinking Idle means 'waiting' rather than 'not started'.
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
✓
The BGP session is not established; possible misconfiguration or reachability issue.
The output shows that neighbor 10.10.10.2 is in the Idle state with zero messages sent or received, indicating the BGP session has never been established. This typically results from a misconfiguration (e.g., wrong neighbor IP, incorrect AS number, missing update-source) or a Layer 3 reachability issue preventing the TCP connection on port 179.
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 neighbor is administratively shut down.
Why it's wrong here
An administratively shut neighbour shows the state "Admin" or "Idle (Admin)", not plain "Idle". The Idle state here reflects no active session attempt, typically from no route to the neighbour or a misconfigured update-source. Shutting a neighbour is done with the neighbour shutdown command.
- ✓
The BGP session is not established; possible misconfiguration or reachability issue.
Why this is correct
The neighbour 10.10.10.2 shows State/PfxRcd as Idle with zero messages received and sent, meaning no BGP session was established. This points to misconfiguration or a reachability problem rather than an established peer, satisfying the stem's diagnostic constraint.
- ✗
The neighbor is in the process of establishing the session.
Why it's wrong here
Active, Connect or OpenSent indicate session establishment in progress; Idle is the initial state before any TCP connection attempt. The zero MsgRcvd and MsgSent counters confirm no BGP messages have been exchanged, so establishment has not begun. Idle here points to reachability or configuration failure.
- ✗
The neighbor has sent all its prefixes and is waiting for updates.
Why it's wrong here
A neighbour that has sent all prefixes and is awaiting updates shows Established with a PfxRcd count, not Idle. Idle means no session exists at all, so no prefixes could have been received. The zero counters and 00:00:05 uptime confirm the session never came up.
