Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
show pim neighbor
Why this is correct
This command displays all active PIM neighbors, interfaces, and uptime, which confirms hello message exchange.
- ✗
show mpls lsp
Why it's wrong here
This verifies MPLS Label Switched Paths, not multicast routing protocol adjacencies.
- ✗
show rpc statistics
Why it's wrong here
This is unrelated to PIM neighbor state.
- ✗
show igmp group
Why it's wrong here
This command shows IGMP membership reports on interfaces, not PIM router-to-router adjacencies.
