BPG with 32bit AS

RouterOS Forwarding Protocols
1

Hi all,

there are any way to work with 32bit AS number with routerOS ?
When I try to use a number like 262600 I get the following message: “Error in AS - decimal number in range [1;65535] expected!”

thanks!

Hi,
It appears that even routing-test doesn’t support 32-bit as numbers. I would write that as a request in the RouterOS Beta forum instead.

im still learning about the 4 byte changes to ASNs… isn’t it supposed to be something like xxxxx.xxxxx ?

Hi Eising,

I started this topic on beta forum: http://forum.mikrotik.com/viewtopic.php?f=1&t=31160&start=0.
It was before I have read your response, sorry :frowning:

Thanks!

4 byte AS numbers are supported since v3.12
changelog:
*) routing-test - added support for 4-octet BGP AS numbers;

New AS should be written in format changeip mentioned: xxxxx.xxxxx

Ah sorry about that. The ASDOT format is now deprecated by most RIRs and anyone else that deals with standards. Any idea about if you will start using the now standard ASPLAIN format? Not that it’s a difficult task to convert between the two numbers, but having two number systems seems a bit redundant to me…

EDIT:
Just to briefly cover the difference:
With the ASDOT format, the 32-bit are split into two 16-bit words, where the lower 16-bit are presented as they’ve always been, 0-65535, and the following values will be 1.1, 1.2, 1.3, etc.

With ASPLAIN, the new values are written 65536, 65537, 65538 etc.

This is now the internationally accepted format.

Hi Mrz!
The new AS are written in plain, as Eising mentioned. But to use the actual routing-test version, how can I put the 262600 AS (for example)? The 262600==00002.62600??

I will make tests with this new module.

Thanks!
