Hello,
I'm trying to forward packets between an IPv4 and an IPv6 network using
an
OpenFlow switch. For this, I have to replace the IPv4 header with an
IPv6 header
(and the other way around). I have tried using Open vSwitch and doing a
set-field action on the dl_type field
(actions=set_field:0x86dd->dl_type), but I
get an error that the field is read-only. Is this a limitation in Open
vSwitch
or in the OpenFlow specification? Or is there perhaps another way of
accomplishing this? (without forwarding each packet to a controller and
rewriting them there.)
Thanks in advance.
