Re: [vpp-dev] ip probe or ip probe-neighbor not in my build?
Benoit, Got it, thanks. Humble apologies because I have a few vpp repos on my machine and reported the failure from an older repo thinking it's a latest repo. I found arping on downloading a new VPP repo today. I will play with it.

[vpp-dev] A question about 'dpo_get_next_node()'
Hi, All I'm confused with the function 'dpo_get_next_node()'. The comment says it create a graph arc from each of the child's registered node types to "each" of the parent's. But if the parent_indices is a vector, assertions will be triggered. So it implies that caller must guarantee the next node of parent dpo has only one slot. Is that right ? vec_foreach(pi, parent_indices) <- where i am confused with { edge = vlib_node_add_next(vm, child_node->index, *pi); if (~0 == dpo_edges[child_type][child_proto][parent_type][parent_proto]) { dpo_edges[child_type][child_proto][parent_type][parent_proto] = edge; } else { ASSERT(dpo_edges[child_type][child_proto][parent_type][parent_proto] == edge); } }Best Regards,Yacan
