Re: [Idr] Fwd: I-D Action: draft-sas-idr-maxprefix-outbound-00.txt

Hi Melchior

Thanks for the quick response!

For both inbound and outbound direction we have today the option to set
prefix limit and threshold for the peer disconnect scenario, so now we
would add a 3rd parameter is your suggestion.

I agree and that makes sense.  With this option when the limit hits and we
are clipping over the limit it would be possible to also do the warning
flag with it so we are logging when clipping and maybe even number of
routes clipped in the log message.

If you have a GitHub for the draft I would be happy to co-author the draft
and provide any additional feedback.

Kind Regards

Gyan
