Implementing Cisco Service Provider VPN Services (SPVI) — Question 11

You are troubleshooting ARP connectivity issues for an Ethernet interface on an IOS XR network that runs IS-IS. You verify that the IGP protocol is running, but an
ARP entry has not yet been created.
Which action should you take?

Answer options

• A. debug ping packets
• B. debug ARP
• C. ping the connected neighbor
• D. verify the RIB table routes

Correct answer: C

Explanation

The correct action is to ping the connected neighbor (option C), as this will initiate the ARP process needed to create an ARP entry. The other options, such as debugging ARP or ping packets, do not directly establish connectivity with the neighbor, and verifying the RIB table routes does not address the ARP issue at hand.
