Summary. This chapter describes the Open Shortest Path First (OSPF) routing protocol support in RouterOS. OSPF is Interior Gateway Protocol (IGP) and distributes routing information only between routers belonging to the same Autonomous System (AS). OSPF is based on link-state technology that has several advantages over distance-vector protocols ...
OSPF configuration on PPP interfaces often is a subject to misunderstanding. You need to keep in mind two things: There is no need to explicitly configure an interface in "/routing ospf interface" to start running OSPF on it. Only "routing ospf network" configuration determines whether the interface will be active or not.
action to perform on route matching the rule. accept - accept the routing information. discard - completely exclude matching prefix from further processing. For incoming filters, 'discard' means that information about this route is completely lost. jump - pass control to another filter list that should be specified as 'jump-target' parameter.
Summary. Bidirectional Forwarding Detection (BFD) is a low-overhead and short-duration protocol intended to detect faults in the bidirectional path between two forwarding engines, including physical interfaces, sub-interfaces, data link (s), and to the extent possible the forwarding engines themselves, with potentially very low latency.

OSPF routes redistribution, summarization and stub area complex example. Packages required: routing. Let's look at the network topology shown below. We have three routers connected to each other via ethernet. Routers R0 and R1 are MikroTik RouterBOARDs running RouterOS 3.25 and router R2 is Cisco 2611. R3 can be any other router, so cisco is ...
This example explains how to use multiple gateways with one taking over when first fails. It begins with adding the gateways. Set bigger distance value for the secondary one, and check-gateway for the first one: /ip route add gateway=192.168.1.1 check-gateway=ping. /ip route add gateway=192.168.2.1 distance=2. That's all, there are no more steps!
