Numbering the aliases is obsolete. Now we glom them into one big string
like this:
NMASK="netmask 0xffffff00"
ifconfig_bce0_aliases="inet6 fe80::2 prefixlen 64"
ifconfig_bce0_aliases="$ifconfig_bce0_aliases inet $NETNUM.100 $NMASK"
ifconfig_bce0_aliases="$ifconfig_bce0_aliases inet $NETNUM.101 $NMASK"
ifconfig_bce0_aliases="$ifconfig_bce0_aliases inet $NETNUM.102 $NMASK"
> # all the other addresses
> ifconfig_em0_ipv6="inet6 ${V6NETNUM}::2 prefixlen 64"
> #ifconfig_em0_alias11="inet6 ${V6NETNUM}::3 prefixlen 64"
> #ifconfig_em0_alias12="inet6 ${V6NETNUM}::4 prefixlen 64"
If you don't want to route the v6 addresses on your LAN, put them on the
loopback lo0 rather than a real interface.
