Static routes work ok (route + 2x routing rules with lookup in another table) but the wiki says: Ping (traceroute as well) uses only main routing table for route lookup. High level design of the test environment. On Linux VRF is implemented by (among other things) placing routing rule to search special table "l3mdev-table". By default this rule is placed with pref value of 1000, while one of the default rules - local - have pref value of 0, meaning it's associated routing table is searched first. Or you could have a separate management-VRF of some sort, which then will be isolated from other VRF's / main-routing-table etc,etc This is only possible when leaking a route and gateway from the "main" routing table to a different routing table (VRF). 100.

Additional: Even with /system/logging/add topics=route nothing appears in the logs Can add a mangle rule setting a routing mark OK, but still can't add a route rule Scenario is that I have the Mikrotik sitting behind a cable router which does NAT for me, so everything on the Mikrotik is straight routing and no NAT. VRF makes connected routers to be in a table route, instead of being in the main table. From a configuration point of view, the biggest differences are routing table limit increase, routing table monitoring differences, and how routes are added to specific routing tables (see next example) v7 introduces a new menu /routing route, which shows all address family VRF's should be totally separate from the main routing table.

For those that do not use VRF but use manually created route tables, it would be very convenient when there would be an option to import Connected routes into a newly created table (so they can be distributed using BGP). Only the VLAN interface is in this new table, the main physical interface is in the main table. I want to leak the new directly connected route to my main table. Search.
