Hi Alexander,
No in my example I need to modify parameters of route X, based on parameters of route Y. That seem to be impossible in current versions of network codes (other than via external controller) adam netconsultings.com ::carrier-class solutions for the telecommunications industry:: From: Alexander Arseniev [mailto:[email protected]] Sent: Monday, March 13, 2017 12:28 PM To: [email protected]; [email protected] Subject: Re: [j-nsp] conditional route import Hello, You can do it easily in BGP Route Reflector export policy coupled with other features like ORR and NH rewriting. There could be complexities with PE config (obviously, the PE would prefer eBGP route direct from CE vs iBGP from RR) but they can be overcome with routing-instances.

Can't find it documented anywhere and it's not working, but I'm just curious what are your thoughts on the concept of general routing behaviour programmability using routing information. I need the network to reprogram itself based on routing events without the YANG/NETCONF complexity. And for that I'd need a route and it's specific parameter or a set of parameters to be used as an instruction or a trigger. I'd like to be able to use a more general from of condition in routing-policies (or even forwarding filters or QOS-policies). Example: condition_1 if (route = x.x.x.x/x in VRF A) AND (igp metric to NH < 100) then condition_1 == TRUE route-policy 1 if route = y.y.y.y/y AND if condition_1 == TRUE then set local-preference 120 AND accept bgp VRF A neighbour z.z.z.z route-policy 1 in Options: The trigger route can be constructed at the trigger router and advertised into an intended VRF or to a separate "instructions-VRF", dedicated to contain these special purpose routes if we don't want to mix these instruction routes with regular routing information. Or the trigger route could be a regular routing info with a specific set of attributes that we intend to use as a marker of a specific network event that we want to act upon in case it happens. I'd appreciate any feedback. adam netconsultings.com ::carrier-class solutions for the telecommunications industry:: _______________________________________________ juniper-nsp mailing list [email protected] <mailto:[email protected]> https://puck.nether.net/mailman/listinfo/juniper-nsp _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
