The standard way is to configure this in your /etc/rc.conf[.local]:

ifconfig_re0="inet xxx.xxx.yyy.134 netmask 0xffffffnn"
ifconfig_re0_alias0="inet xxx.xxx.yyy.135 netmask 0xffffffff"
ifconfig_re0_alias1="inet xxx.xxx.yyy.136 netmask 0xffffffff"
... etc.

You could make a script to generate the correct configuration lines,
and then include it in your rc.conf:

/etc/rc.conf:

. /path/to/ifconfig_entries.sh

/path/to/ifconfig_entries.sh:
ifconfig_re0="inet xxx.xxx.yyy.134 netmask 0xffffffnn"
ifconfig_re0_alias0="inet xxx.xxx.yyy.135 netmask 0xffffffff"
ifconfig_re0_alias1="inet xxx.xxx.yyy.136 netmask 0xffffffff"

See http://www.freebsd.org/doc/en/books/faq/networking.html#ETHERNET-ALIASES
for more info. Note that aliases should have a netmask of 0xffffffff
(255.255.255.255).
