Note that if no reply is received to a reoptimization PREQ, the existing path is kept anyway (until it timeouts itself)Īctive-port-type ( read-only: wireless | WDS | ethernet-mesh | ethernet-bridge | ethernet-mixed Default: ) Turning on this setting is useful if network topology is changing often. Whether to send out periodic PREQ messages asking for known MAC addresses. Whether this interface is a portal in the mesh network How long to wait before propagating a RANN message. Hwmp-rann-propagation-delay ( number Default: 0.5) Lifetime for routes created from received RANN messages How often to send out HWMP+ RANN messages Note that for subsequent PREQs the waiting time is increased exponentially How long to wait for a response to the first PREQ message. Hwmp-preq-waiting-time ( time Default: 4s) How many times to retry a route discovery to a specific MAC address before the address is considered unreachable

Useful only when hwmp-preq-destination-only is disabled Whether intermediate nodes should forward HWMP+ PREQ message after responding to it.

Hwmp-preq-reply-and-forward ( boolean Default: yes) Whether only destination can respond to HWMP+ PREQ message Hwmp-preq-destination-only ( boolean Default: yes) Lifetime for routes created from received PREP or PREQ messages Maximum hop count for generated routing protocol packets after a HWMP+ packet is forwarded 'hoplimit' times, it is dropped Hwmp-default-hoplimit ( integer: 1.255 Default: ) If disabled, then value from admin-mac will be used as the MAC address of the mesh interface else address of some port will be used if ports are present

Software versions: 3.28+ (earlier versions are incompatible)Īdmin-mac ( MAC address Default: 00:00:00:00:00:00)Īdministratively assigned MAC address, used when auto-mac setting is disabledĪrp ( disabled | enabled | proxy-arp | reply-only Default: enabled) Note: Prerequisites for this article: you understand what WDS is and why to use it! So you can use simple Ethernet based distribution system, or you can combine both WDS and Ethernet links! HWMP+ mesh routing supports not only WDS interfaces, but also Ethernet interfaces inside the mesh. Note that the distribution system you use for your network need not to be Wireless Distribution System (WDS). The HWMP+ protocol however is not compatible with HWMP from IEEE 802.11s draft standard. It can be used instead of (Rapid) Spanning Tree protocols in mesh setups to ensure loop-free optimal routing. It is based on Hybrid Wireless Mesh Protocol (HWMP) from IEEE 802.11s draft standard. HWMP+ is a MikroTik specific layer-2 routing protocol for wireless mesh networks. 8.2 Problematic example 2: wireless modes.8.1 Problematic example 1: Ethernet switch inside a mesh.
