IPv6 & CARP = doesn't apply requested IP

HelLo!,

Might be late for me, but I find an odd scenario setting up IPv6 CARP IP.

Basically I set the IP as: fe80:73:65:6d:6c:61:62:1

It gets configured as: fe80:0:65:6d:6c:61:62:1 (checking via ifconfig).

What gives?

The 54 bits following the fe80/10 must be zero. You only get to pick the last 4 words, e.g.

fe80::006c:0061:0062:0001

Maybe you really want

fea80::7365:6d6c:6162:1?

It's 16 bit words between the colons, not bytes.
