But you can pin down these into the config:
no ip address
ipv6 address FE80::FEED:BABE link-local
r101#sh ipv6 int
Ethernet0/0 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::FEED:BABE
No Virtual link-local address(es):
if you are to configure the addresses manually anyway - you could
manually configure the link-locals (too|instead) ?
