RE: filtering /48 is going to be necessary

Splitting the allocation can be done for many reasons. There are known cases where one LIR operates multiple separate networks, each with a separate routing policy. They cannot get multiple allocations from the RIR and they cannot announce the whole allocation as a whole because of the separate routing policies (who are sometimes required legally, for example when an NREN has both a commercial and an educational network).

If they have two different routing policies and need two different allocations, why not just have two different LIRs? It makes things a lot easier than spending untold weeks or time trying to work out which corner cases should be supported by policy and which should not. No? Leo
