Hi all, I am trying to get ARP events from VPP and found that there is a 'wildcard-ip4-arp-publisher-process' process which could be used. To use this, I registered a client using API `vpp.api.want_ip4_arp_events` using 0 as IP address argument. I could see that registration is happening and `wc_arp_set_publisher_node` function was getting invoked, as it should.
But the node was not reporting any ARP events to the client. Looking through the code, the main function in the node, `wc_arp_process (vlib_main_t vm, vlib_node_runtime_t rt, vlib_frame_t * f)` is not getting invoked. I also registered another client, using `vpp.api.want_ip4_arp_events` but using a valid IP addres as IP address in argument. Here I'm able to get the ARP events in the client process from ip-route-resolver-process, as expected. I just need to figure out why wildcard-ip4-arp-publisher-process is not reporting ARP events, though ip-route-resolver-process is doing so. Thanks and Regards, Raj
