Two IP address for One 6455

Hi,

Thanks for your post.

In general, NDK stack do not support configuring IP addreses to run 2 instances in parallel on the same subnet but it is possible to get two IP addresses on two different EMAC interfaces provided they both are in the different subnet.

But in one case, it is possible only in listening mode, I mean, UDP receive sockets mapped to two different IP addresses but to the same UDP port on each IP address. For more details on this usecase, please refer the below E2E posts:

Please check this too, NDK FAQ,

Also, the Network Interface Management Unit (NIMU) architecture is introduced which will provide an interface between the stack and the device drivers through which the stack can talk to multiple instances of a single or various device drivers concurrently. So, I think for this particular case they would want to use 2 different interfaces, obtaining an IP address for each, then set up a VLAN on each interface.

Thanks & regards,
