Not exactly. I had followed the same reference to this text as well. My 
question was more about what happens to the message that gets forwarded (due 
to the message processing continuing as normal) on the next node that gets 
the message with the SRLG collection flag set but without the RRO. Does it 
add an RRO? Does it drop the message? ...

Thanks
