Are you trying to use setsockopt with an IP address configured in VPP? VPP and the kernel are independent, isolated, network stacks. Sockopts are a purely kernel-network-stack concept and have no effect on anything VPP does.
Even if you were trying to interact with an IP address in the kernel network stack, we discourage the use of syscalls as much as possible since they are quite expensive. If you are trying to create the equivalent of a socket in VPP, you need to register a node for the traffic. For UDP this means hooking in to traffic that matches the destination UDP port. For IPIP that would mean registering a node that hooks into the IP protocol number for IPIP. Cheers, Chris.

Hi Vpp Developers, Following are the few observation about the issue 1. setsockopt() APi is returning error 'eaddrnotavail' . 2. If we don't assign the ip address to interface then we are not getting above error.But in this case it is not considering this interface for igmp functionality. Please provide any input on this.

Hello Members, I am getting error while Binding the socket to vpp interface. it gets bind perfectly with Linux interface ,but when i pass the vpp interface it gives the error. We also tried to debug the issue with the code given at /vnet/map/examples/health_check.c. But still it giving the same problem. I am creating socket following socket() API if ((sd = socket (AF_INET, SOCK_RAW, IPPROTO_IPIP)) < 0) { perror ("Failed to get socket descriptor "); exit (EXIT_FAILURE); } i am binding the socket with following setsockopt() Api. if (setsockopt (sd, SOL_SOCKET, SO_BINDTODEVICE, (void *) &ifr, sizeof (ifr)) < 0) { perror ("SO_BINDTODEVICE failed"); exit (EXIT_FAILURE); } Can anyone help me on this Regards, Deepak =====-----=====-----===== Notice: The information contained in this e-mail message and/or attachments to it may contain confidential or privileged information.
