I think /32 can reflect correctly what is in PIONIER RRD MA. It has only 
single interface in each of these networks in metadata config file. So 
MDM hLS advertises /32s for these two IPs. Or you would expect something 
different here?

Could you Nina help us here?

Maciej - can you give us some info on the current summarisation in MDM 
hLS? You used the code provided by I2 as it was or made some changes?
