[Idr] Re: WG adoption call for draft-abraitis-bgp-version-capability-08, to end September 25

[Acee Lindem <[e-mail]>]

I support WG adoption. It useful to be able to discover the deployed software versions to better know the attendant features and bugs. 

Thanks,
Acee

In short: there are already 4 or 5 open-source implementations supporting this BGP capability, and Wireshark (maybe more from the observability tools) has it too. The motivation is quite simple: very trivial and fast to implement while giving a useful information set for the operators.
