Create sane defaults for 'announce_whole_subnet'-options..

If it does not help, please fill information below:

• Your operating system name and version?
  root@fastnetmon:# lsb_release -a

To work with 'announce_whole_subnet'-options, we must configure each existing subnet in /etc/networks_list. For IPv4 this is doable, but for IPv6, that's quite a long list.

I would love to see a default option where the default IPv4-subnet would be a /24 and the default IPv6-subnet would be a /48. Those are the minimal accepted sizes on the internet, so they seem like a sane default.

Thanks!

Hello!

Thank you for reporting!

The very first issue here that we do not support IPv6 per subnet announces at all:

fastnetmon/src/actions/gobgp_action.cpp

Line 147 in 18fea2e

logger << log4cpp::Priority::ERROR << "Sorry but we do not support IPv6 per subnet announces";

We need to start from covering this gap first.
