Which well-know multicast group is joined by all PIM-enabled routers to receive RP mappings?
- 224.0.0.13
- 224.0.1.39
- 224.0.1.40
- 224.0.0.2
| Answers Explanation & Hints:
RP mapping agents advertise the RP mappings to the well-known multicast group address, 224.0.1.40 (Cisco-RP-Discovery). Advertisements are sent every 60 seconds by default, or when changes are detected. All PIM-enabled routers join 224.0.1.40 and store the RP mappings in cache. |
