I’m interested to know if there is any way a route origin can be altered.
For example I add a network to be advertised to the ISP using the network command. That will mark the route origin as I. Can I change that to E for example before sending the advertisment? It’s possible in IOS/JUNOS by using route maps.
It’s not possible. I emailed Mikrotik support recently, and they said it will may be added in the future, but it seems we should not expect to find it soon.
In my situation I need to set route-origin to IBGP for the routes dynamically assigned to radius that otherwise appear as “incomplete”.
