No, the link local addresses are already assigned.  The only thing route6d 
does is to basically create a mapping between the default route and the 
link local address of the next-hop router, i.e., discover the link-local 
next-hop address.

Rather silly use of route6d, if you ask me.  Just ask the ISP to configure 
fe80::1 as the address, or find the address of the neighbor otherwise 
(e.g., it can be calculated for v6-over-v4 tunnels by yourself).
