There was also in the past fec0::/10. For BGP updates you should be safe to filter out FC00::/6. Unless I've missed something, RFC4193 lays out FC00::/7, not the /6. So while FE00::/7 may yet be unallocated, I don't think I'd set filters in that fashion. Reasonably, wouldn't it be more likely to permit BGP advertisements within the 2000::/3 range as that's the "active" space currently?
FF00::/8 are multicast, FE80::/10 are reserved for link-local. In the past you had FEC0::/10 as a kind of private addresses. Allowing 2000::/3 is fine as well. Btw - what are the estimates - how long are we going to be within 2000::/3? -- Grzegorz Janoszka
