Hello, You can disable autoprepending of your side's AS by using rs-client and prepend it manually in the place you like. On Thu, Mar 21, 2019 at 11:41 AM L Ken <playernkc@gmail.com> wrote:

Hi,

As mentioned in https://bird.network.cz/pipermail/bird-users/2017-December/011774.html, BIRD 2.0 calls export_filter before LOCAL-AS is set to bgp_path.

In BIRD 1.6, following export filter create AS path "10001 10002 10003": protocol bgp bgp1 { # some required bgp config here

local as 10003; export filter { bgp_path.prepend(10002); bgp_path.prepend(10001); } }

The same filter in BIRD 2.0 create AS path "10003 10001 10002" : protocol bgp bgp1 { # some required bgp config here

local as 10003; ipv4 { export filter { bgp_path.prepend(10002); bgp_path.prepend(10001); } } }

Is there any way to "prepend" AS to Local-AS in BIRD 2.0 with result same as 1.6?

Thanks, --- K
