JNCIP-ENT IP Multicast Practice Question
A network engineer troubleshoots an issue where multicast data packets are being dropped due to an RPF (Reverse Path Forwarding) check failure. The unicast routing table uses OSPF, but MBGP is deployed for multicast routing. Which operational command should the engineer use to verify the multicast RPF path for a specific source IP?
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
✓
show route rpf 192.0.2.1
When MBGP is used for multicast RPF separate from unicast routing, the command 'show route rpf <source-ip>' helps check which routing table and next-hop is used for the multicast RPF check.
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 msdp rpf 192.0.2.1
Why it's wrong here
MSDP has its own peer checks, but RPF lookups for PIM use the multicast routing table verified with 'show route rpf'.
- ✗
show pim rpf-table 192.0.2.1
Why it's wrong here
This command does not exist in Junos.
- ✓
show route rpf 192.0.2.1
Why this is correct
The 'show route rpf' command displays the RPF lookup results and path used by multicast routing.
- ✗
show multicast rpf-failure
Why it's wrong here
While drop counters exist, 'show route rpf' is the correct command to check the active RPF route.
