It is a trap. The first entry is the key, STAR, G entry. It is ASM despite using 232/8. A, C

You can configure Junos OS to accept any-source multicast (ASM) join messages (*,G) for group addresses that are within the default or configured range of source-specific multicast (SSM) groups. This allows you to support a mix of any-source and source-specific multicast groups simultaneously. So it's really a trap, using SSM reserved range for ASM traffic.

The (*,G) entry indicates that is ASM. Also the Join sent to Source and Prune sent to RP means that traffic is flowing through the SPT
