[dpdk-dev] Query on the old patch: examples/l3fwd: use reserved IPv4/IPv6 addresses

[Hemant Agrawal]

Hi Stephen,
              In one of your old patch, you have changed the default IP addresses to the range of 192.18.0.0 citing RFC 5735.

examples/l3fwd: use reserved IP addresses

however, in the RFC, I see the range as 198.18.x.x.  Was this deliberate ? Or, I am misreading?

https://tools.ietf.org/html/rfc5735
198.18.0.0/15       Network Interconnect
                    Device Benchmark Testing   RFC 2544<https://tools.ietf.org/html/rfc2544>

Hemant

Good catch, this is a typo in my patch.


   198.18.0.0/15 - This block has been allocated for use in benchmark
   tests of network interconnect devices.  [RFC2544] explains that this
   range was assigned to minimize the chance of conflict in case a
   testing device were to be accidentally connected to part of the
   Internet.  Packets with source addresses from this range are not
   meant to be forwarded across the Internet.
