Hi, In the latest VPP code, in icmp6_router_solicitation - the code checks for radv->mcast_adj_index and if it is "0" - it flags an error ICMP6_DST_LOOKUP_MISS.
However, in ip6_neighbor_sw_interface_add_del - when the radv_info_t structure is getting initialized - when mcast_adj_index is allocated using adj_mcast_add_or_lock - it is returning adjacency index as zero. That left me puzzling whether adjacency index 0 is not valid (I guess it is ok to have adj index as zero). Please correct me if I am wrong. Thanks, -nagp
