NEW QUESTION # 103
A network administrator is troubleshooting a DMVPN setup between the hub and the spoke. Which action should the administrator take before troubleshooting the IPsec configuration?
Answer: B
Explanation:
Before troubleshooting IPsec in a DMVPN deployment, the administrator should verify the GRE tunnel operation. DMVPN is built from multipoint GRE, NHRP, routing, and usually IPsec encryption. IPsec protects the tunnel traffic, but the logical tunnel and overlay reachability must be valid first. If the tunnel interface is down, incorrectly addressed, or unable to carry GRE traffic, troubleshooting crypto maps or ISAKMP will waste time because encryption cannot fix a broken overlay. After the GRE tunnel state is validated, the administrator can confirm NHRP registration and resolution, routing adjacencies, and then IPsec security associations. ISAKMP and crypto map troubleshooting are relevant only after basic tunnel operation is known to be correct. NHRP is also critical in DMVPN, but the question asks what to do before troubleshooting IPsec configuration; the first prerequisite is to verify that the GRE tunnel itself is functioning.
This layered troubleshooting order follows Cisco operational practice: confirm transport reachability, then tunnel interface behavior, then NHRP and routing, and finally cryptographic protection.
