Hi Aman,
I remember when FRR version 2.x and 3.x, the ZAPI didn't keep the backward
compatibility even if the version of ZAPI is the same (version 4)....

Thank you for your explanation!
Yeah, it is very interesting for me! Could you share us your patches?
Also, how about discussing this topic on (a new) GitHub issue? Thread of this
topic had become long, and I guess GitHub issue is more easier for GoBGP users
to find this topic.
Thanks,
Iwase

Thanks for your information!
Hmmmm... just my anxiety...
When I implemented the FRR/Zebra support (based on the Quagga/Zebra
integration), I had some compatibility problems of the ZAPI messages. Along
with the update of FRR, the ZAPI message structure was changed without the
backward compatibility, so I dropped to support FRR version 2.x. Similar to
this problem, I'm worried if the ZAPI version 5 will be changed unexpectedly
near future (version 5 structure is not yet stable?)...
Thanks,
Iwase

Hi Aman,
Sounds great!
To use the ZEBRA_VRF_LABEL command, which version of FRR is required?
"stable/3.0" branch, GoBGP currently supports only FRR version 3.x, still uses the ZAPI version 4,
then we need to use "dev/4.0" or "master"?
Thanks,
Iwase
