Because you may not have an option, if you're IPv6 only, vendors (e.g.
junos) may expect you to punch it manually. Of course most of us punch
it manually as loopback0 IPv4 to have more control over outcome.
Question is legitimate and represents change where previously used
mechanisms do not apply, therefore OP is right to ask 'well what
should I do now'.
