You pretty much sum up whats going on, except in this case RIP is being 
used as the IGP for this customer VRF spread across some peices of 
equipment.

I was thinking more of the ability to specify a prefix-list to limit the 
number of /30 /32 route announcments you migh end up carrying in a 
customer vrf.
Having to specify it per interface removes the ability to have an 
"umbrella" filter for the entire vrf rip instance with a specific 
interface filter.

My other question is whether this is supported in ospf or is-is.
