Please do not split up smaller than /48. You will be heavily filtered. If you have reasonable connectivity between sites, get something larger than /48, perhaps /44 or even /32 if you are a hosting provider. Announce /48 for each site and announce each /48 plus a covering /44 or /32 or whatever you were given. That way you will be reachable even from those providers who filter by database objects. On the other hand, if the sites each live in their own world, consider whether you can live with PA space from whichever provider you have at each site. If you must have PI, get a separate /48 for each site if possible. Akamai can get away with taking a /32 and splitting it to deaggregated /48's, because any ISP which cannot reach Akamai is going to get complaints from its customers. If you have that kind of clout, you can do whatever you want. For the rest of us, being strict in what you send and liberal in what you accept is the only -- and strict means no deaggregation without covering routes or separate database objects. /Benny _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
