So, a small nuance, the second recursive, addresses the first DNS site @anav's question was "why would you want to use ECMP" while yours was (apparently) "can I use ECMP or do I have to use distinct distance values"?In ROS 6, you had to specify multiple gateways for the same destination as a list in a single route to get ECMP; in ROS 7, it is enough to configure multiple routes with same destination and distance to get ECMP. Post Property Description; action (accept | discard | jump | log | passthrough | reject | return; Default: passthrough): action to perform on route matching the rule.

Given that route print detail shows things like gateway-status=10. How would I apply recursive failover by checking for packet loss? I suppose the script logic would be: 1. 6) Don't know why, but it probably pings above two hosts with LTE1 interface, The "recursive routing" is just an incorrect shortcut for "recursive next-hop search"; the search processs has nothing to do with the actual packet flow. Sebagai tambahan, yang sering menjadi kendala adalah mekanisme check-gateway hanya dapat melakukan pemantauan gateway terdekat, sehingga jika yang terjadi masalah di atas jalur ISP-A misalnya, paket data akan tetap dilewatkan melalui ISP-A, sebab router masih menganggap ISP-A reachable. MikroTik RouterOS v7 dual DHCP WAN recursive failover w/ PCC load-balancing; and recursive ECMP Raw. Recursive routing allows you to create a route with a defined next hop that is not actually directly adjacent to the router.
