>Description:
Using FreeBSD-4.5-STABLE from ~2 months ago, I had no problems
setting several IP aliases on my xl0 interface by setting the
following in /etc/rc.conf:
ifconfig_xl0="inet 172.25.124.236 netmask 255.255.255.0"
ifconfig_xl0_alias0="inet 172.25.124.237 netmask 255.255.255.0"
ifconfig_xl0_alias1="inet 172.25.124.238 netmask 255.255.255.0"
ifconfig_xl0_alias2="inet 192.168.172.1 netmask 255.255.255.0"
With a current kernel however, after reboot only one or two of these
IP addresses are actually set. The other IP addresses are unset.
>How-To-Repeat:
See above... On my -STABLE system, at least :-(
>Fix:
Manual execution (after the machine has booted) of:
# ifconfig xl0 down
# ifconfig xl0 inet 172.25.124.237 netmask 255.255.255.0 alias
# ifconfig xl0 down
# ifconfig xl0 inet 172.25.124.238 netmask 255.255.255.0 alias
# ifconfig xl0 down
# ifconfig xl0 inet 192.168.172.1 netmask 255.255.255.0 alias
# route add -net 172.25.124.0 -interface xl0
seems to help. It appears as though adding an alias was only possible
while the interface has been brought down.
