It also scales better from the SP point of view. If you have 1000 L3VPN 
services on your PE node using OSPF to the customer that would require a lot of 
memory for the multiple LSDBs and a lot of CPU for the SPF calculations.
BGP is nicer but the reality is that many enterprises don't have the know-how.

Of course, technically you could use almost any routing protocol.
OSPF and IS-IS would require more configuration and maintenance, BGP even more 
still.

I think this is a pretty good example though of how RIPv2 is probably the most 
appropriate for the job. It doesnt require further configuration from the 
provider side as new sites are added and is very simple to set up and maintain.
