It uses the xrl/interfaces/fea_ifmgr.xif XRL interface:

start_transaction -> tid
create_interface ...
set_...
create_vif
set_...
create_address4
set_...
create_address6
set_...
commit_transaction

The interfaces template etc/templates/interfaces.tp contains the
particular XRLs invoked when the interface-related configuration is
changed. Note that any changes to the configured interface tree
are wrapped inside "start_transaction/commit_transaction".

Do you mean the add_vif methods declared inside fea/ifconfig_set.hh?
Those are used inside fea/ifconfig_set.cc
