Hi, Yes, in version 2 the filter is applied before the prepend is made during exporting. With tcpdump try to use "-s0 -v" options, it should "decrypt" the bgp messages well. On Tue, Aug 4, 2020 at 9:42 AM Julien Sansonnens <julien@jsansonnens.ch> wrote:
Dear all,
using bird 2.0.7
I'm a bit confused with the output of "show route export". I'm exporting a full table to a downstream. I'm expecting to see my own AS as the first AS in AS PATH but it will not show in "BGP.as_path" If I prepend it, then it appears on the output.
I don't know if it's related to display, or if my AS is really not added to the PATH. Perhaps it is added later in the process, before leaving my router ?
How can I check this? I tried with "debug", but to my knowledge, it is not possible to display route details. I thought about doing tcpdump, but I haven't found out how to interpret the result correctly and see the AS PATH. Would you have a clue on how to see exactly what is being exported on an interface?
thanks a lot Julien
