Does Bird supports AS_Trans 23456

[gerta toli]

HI Ondrej,


This is my configuration

protocol bgp eBGP4byteASN {
debug all;
   import all;
   export filter out;
   local as "my-4byteASN";
   neighbor 192.168.0.1 as 65535;
   source address 192.168.0.2;
}


So my peer 192.168.0.1 understands only 2byte ASN , but I have 4byte ASN. ASN_Trans is used in case of such scenario by the 4byte ASN routers. So  supposedly, Bird should send open message using the ASN 23456, since it knows that it is peering with an old 2byteASN router. The error im showing is below:

2018-08-27 15:19:03 <TRACE> eBGP4byteASN: Started

2018-08-27 15:19:03 <TRACE> eBGP4byteASN: Startup delayed by 300 seconds

So my question is, does Bird supports using this ASN_Trans? How can a 4byte ASN bird router establish a session with a 2byte ASN router?


Thanks,

Gerta

Hello

What exactly is your configuration and what exact error message you get
in log and/or in 'show protocols'?
