[SR-Users] extra_id_pv parameter

[Bruno Bresciani]

Thank's Klaus,

now I understand how to use the extra_id_pv parameter... I already use the
rtproxy_manage in branch_route to process every branch separately, but I
was with difficult to understand how set extra_id_pv to every branch of
forking. Your example helped me to eliminate my doubts (I think).

Best Regards
