IPv6 prefix set

[Damien Clabaut]

Hello,

I am trying to use prefix-set inside a filter in IPv6:
filter my_filter6
prefix set my_prefixset6;
{
  my_prefixset6 = [aaaa:bbbb:100:ff::/56];
  if (net ~ my_prefixset6) then {
    bgp_local_pref = 104;
  }

  accept;

}

But I get the following error:

birdc6
BIRD 1.6.3 ready.
bird> configure check

Invalid network prefix: aaaa:bbbb:100:ff::/56.

Am I doing anything wrong ?

Also, the prefix set is dynamically updated via script, is there a 
correct way to handle the case where it is empty ?

Or should the scripts comment the definition of prefix-set and the 
complete "if" block ?

Regards,
