How to announce attributes with path-information?

[dilusi]

Is your feature request related to a problem? Please describe.
I'm trying to send multiple NLRI with the same attribute via "announce attributes", so that I can reduce the number of lines sent to the stdout pipe.
I tried the following commands, but the path-information (path-id) is dropped.

neighbor fdbd:dcff::1 announce attributes path-information 1.2.3.4 next-hop 5.5.5.5 community [65535:65282] local-preference 200 nlri 1.0.0.1/32 1.0.0.2/32

Sorry, you are not providing enough information. Could it be that path-information was not negotiated with the peer?

Thanks for the reply! path-information is negotiated, and I was able to announce this route with path-information via the following command:

neighbor fdbd:dcff::1 announce route 1.0.0.1/32 path-information 1.2.3.4 next-hop 5.5.5.5 community [65535:65282] local-preference 200

The exabgp config is:

neighbor fdbd:dcff::1 {
	router-id 1.1.1.1;
	local-address fdbd:dcff::2;
	local-as 300;
	peer-as 300;

	family {
		ipv4 unicast;
		ipv6 unicast;
	}

	capability {
		add-path send/receive;
		route-refresh;
	}

	api {
		processes [ announce-routes ];
		neighbor-changes;
	}
}
process announce-routes {
	run /app;
	encoder text;
}

The scenario is that, we have ~50k routes and 1k unique attributes. I'd love to send 1k commands instead of 50k commands to exabgp, so that the overall performance is improved (less impact from stdout pipe)

Thanks, I will have a look

Should now be working.

Thanks Thomas, what's the ETA for a new tag with this fix?

For 4.2 I have to review or revert a third party patch which changes the RIB so it is holding any new release ATM.
