Well, curl does not cope well with IPv6 link local.

I found something which works:

0. Use "ip address show dev $IFNAME" to get the interface -numerical- 
indentifier.

$ ip a s dev eth1
2: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP 
qlen 1000

1. curl -g -6 http://[LL-ADDR%25NUMERICAL-ID]/

%25 is an escaped % sign, with numerical identifier 2 it looks like:

$ curl -6 -g http://[fe80:0000:0000:0000:0302:03ff:fe04:0506%252]/
