BGP 4-Byte AS in routemap community

Hi all,

Gaia (R80.20+) has 4-byte AS support, this I know. However, this does not work for a routemap with a community attribute:

set as 4200001201

set routemap FOO id 10 on

set routemap FOO id 10 action community 99 as 64086.60955 on

CLINFR0409 Invalid integer for range check: 64086.60955
set routemap FOO id 10 action community 99 as 64086.60955
-------------------------------------------^^^^^^^^^^^^^^

Same if I try it with the long version:

set as 4200001201

set routemap FOO id 20 action community 99 as 4200001201 on
CLINFR0409 Invalid integer for range check: 4200001201
set routemap FOO id 20 action community 99 as 4200001201
-------------------------------------------^^^^^^^^^^^^^

The R80.20 (R80.40, and even R81.10) Gaia Advanced Routing Guide even hints at the lack of 4-byte AS support:

(From the guide):

set routemap <Name of Route Map> id {<1-65535> | default} action aspath-prepend-count <1-25>
community

<Community ID> as <Community AS Number 1-65535> {off | on}

Does anyone know if this is planned to be updated?

Thanks!

We do not support 4-byte ASes in communities. I think they are defines as part of large-communities RFC-8092. Please open a RFE.

I contacted our SE for an RFE.
