what is the Routed /64?

[user71]

Hi. I recently create 6to4 tunnel and get Routed /64 Routed /48 Prefixes in Tunnel Details. I have 8 subnets that's because i choose Routed /48. and i don't understand what is the Routed /64? why you give me that? In /48 i have many /64

today, somebody decide to scan my not usable routed /64 prefix. I dont't use it and don't have specific route for it. the packet arived to my router, router lookup up in routing table for /64 prefix and send it to default route, back to you 1/128 then there is a route loop....

Everyone gets a /64 by default.  If you don't need it, don't use it.
