Hello!

Is it possible to advertise routes to another AS tagged with no-export community?

It seems that append-bgp-communities=no-export in output routing filter prevents the route from being advertised, nevertheless is is listed in "routing bgp advertisements".

You can't to eBGP peer. Because no-export menas that route is not exported to external AS.

If this is the case how is one supposed to signal to their upstream that said route doesn't need to be exported? Pretty sure other platforms let you do it.

I can see your point if the community was added via a inbound filter.

Typically upstream providers define communities for specific actions:

for example
333:1 = prepend once
333:2 = prepend twice

333:10 = no export

and so on.

Contact your upstream provider for more details.

I encountered the problem when migrating from cisco to mikrotik. I had a route-map which set no-export community (outbound). When I directly translated the route-map to "ip routing filter" outbound chain, the routes disappeared.

I think the no-export community should be used for route filtering before the outgoing "ip routing filter" processing, just set no-export should be passed to the neighbour.

no-export will be passed to the peer in new routing version. But for v6, most likely it will stay as it is.

The mythical "new routing"

Glad I saw this before I replaced another border router with a CCR.

Is there a timeframe for fixing this?

I've opened a support case (no response), but this appears broken in RouterOS 7 but actually does work in RouterOS 6.

May we ask for the progress on this?
