Hello,
I would like to use a round robin aggregation of 2 (or more) gif(4)
interfaces.
For example:
# ifconfig gif0 create
# ifconfig gif0 tunnel 10.16.10.14 10.16.10.12
# ifconfig gif0 10.9.1.1 netmask 255.255.255.255 10.9.2.1
# ifconfig gif0 mtu 1500 up
#
# ifconfig gif1 create
# ifconfig gif1 tunnel 10.16.10.100 10.16.10.12
# ifconfig gif1 10.9.1.2 netmask 255.255.255.255 10.9.2.2
# ifconfig gif1 mtu 1500 up
#
# ifconfig trunk0 trunkport gif0 trunkport gif1 192.168.1.1 netmask
255.255.255.0
ifconfig: SIOCSTRUNKPORT: Protocol not supported
Well, it looks like this functionality isn't implemented yet with gif(4)
driver...
Would it be possible to implement it?
I know pf(4) can also do load balancing, but I find this way less
intuitive as the resulting interface cannot be monitored as easily as a
trunk(4).
Thanks for your help.
