Hey folks Long time user of the software, never sent anything here, today’s my first time I cannot manage to find anything in the user guide of v1/v2/v3 concerning some sort of rt_lookup inside of filters The setup is fairly easy Routers are interconnected heterogeneously, there is a direct BGP session using link local IPv6 on any of these interconnection links Routers announce loopbacks over these sessions with rr client There is some sort of local pref / med set up for better traffic quality Then they all peer with N route reflectors Sharing the “real” prefixes via loopback addresses This works well with gateway recursive mode. There are lot of attributes that we can access inside of filters, what I cannot manage to understand is if it’s possible and how to access let’s say in a filter configured at the RR protocol import/export side - the attributes of the computed gateway - that has been announced on the “underlay” BGP protocol side For example using external access to bird I can $ birdc show route all ::/0 ::/0 unicast [RR] * via 2001:db8::1 on IFACE # No BGP.Med $ birdc show route all 2001:db8::1/128 2001:db8::1/128 unicast [PROTO] * via fe80::1 on IFACE BGP.med: X BGP.local_pref: Y Hope I didn’t miss some context Thanks in advance
