Hi Tobias,

- Add large-communities/scrubbing
I think extended (RFC4360) communities should also be added here.
Another point to add in this section is scrubbing communities from a
received route if the number of attached communities is excessively high
(e.g. > 100).
- Add MAY for scrubbing of attributes
"operators MAY opt to scrub all BGP attributes known to cause service
disruptions"
I would suggest replacing the word "all" with "specific", or to add a
line explicitly clarifying not to scrub unknown transitive attributes.
- Add max-prefix limits and global limits
The global limits seem to offer no real benefit in addition to
per-session limits. The referenced paper mentions Per-Origin AS limits,
not the per-Neighbor AS limits mentioned in the draft. This also seems
to be unimplementable, given that routers act independently on prefixes
they receive.
Kind regards,
Martin
