Hi,
I've been configuring a device with the following rc.conf lines:
ifconfig_le6_name=3D"manee"
ifconfig_manee=3D"fib 5 up"
ifconfig_manee_alias0=3D"inet 185.100.174.221 netmask 255.255.255.0"
ifconfig_manee_alias1=3D"inet 172.31.4.216 netmask 255.255.255.128"
ifconfig_manee_alias2=3D"inet 192.168.124.216 netmask 255.255.255.128"
The result I would have expected is as follows:
manee: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 15=
00
options=3D8<VLAN_MTU>
ether 08:00:27:d3:83:da
inet 185.100.174.221 netmask 0xffffff00 broadcast 185.100.174.255
inet 172.31.4.216 netmask 0xffffffc0 broadcast 172.31.4.255
inet 192.168.124.216 netmask 0xffffff80 broadcast 192.168.124.255
nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: Ethernet autoselect
status: active
fib: 5
Instead I get the following on boot of the box:
manee: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 15=
00
options=3D8<VLAN_MTU>
ether 08:00:27:d3:83:da
inet 185.100.174.221 netmask 0xffffff00 broadcast 185.100.174.255
inet 172.31.4.216 netmask 0xffffffc0 broadcast 172.31.4.255
nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: Ethernet autoselect
status: active
fib: 5
I then tried to run the following command:
ifconfig manee alias 185.100.174.221 netmask 255.255.255.0
ifconfig manee alias 172.31.4.216 netmask 255.255.255.128
ifconfig manee alias 192.168.124.216 netmask 255.255.255.128
Which resulted in the following output:
ifconfig: ioctl (SIOCAIFADDR): File exists
After this I tried:
ifconfig manee -alias
Which seemed to wipe all addresses fro mthe device as expected.
I then started again using ifconfig lines to assign the aliases to the devi=
ce, they all succeed apart from when I get to the 192.168.124.216 one. Whic=
h again outputs the following:
ifconfig: ioctl (SIOCAIFADDR): File exists
Even though running ifconfig only shows the first two addresses configured.
Note: I also have a mgmt interface on fib 0 configured with the ip : 192.16=
8.124.250
>From investigation it seems to somehow be clashing with this, as I am able =
to add a 3rd alias with the following line:
ifconfig manee alias 192.168.125.216 netmask 255.255.255.128
Is it not possible to have two IP Addresses on the same range, but differen=
t addresses on seperate fibs?
Thanks for any help!
Steven
