IESG Benjamin Kaduk: Appendix B #215

Closed stoffi92 closed 4 years ago

Appendix B

  Section 7 defines all Traffic Filtering Action Extended
  communities as transitive extended communities.  [RFC5575] defined
  the traffic-rate action to be non-transitive and did not define
  the transitivity of the other Traffic Filtering Action communities
  at all.

I assume the consequences of changing a community from non-transitive to transitive are well-known (but not to me) and that any operational considerations for mixed deployments are already stated somewhere prominent to someone working with BGP. (Where is that?)

  Section 7.7 contains general considerations on interfering traffic
  actions.  Section 7.3 also cross-references this section.

nit(?): the last "this section" refers to 7.7, not the location of the text I'm quoting from (Appendix B). I misread it the first time.

We need to fix the reference for 7.3 - I think.
The other point about transitive versus non-transitive - I will send to Ben.

Last Comment!!

//doc Transitive vs non-transitive: The IANA assigned extended community is from the transitive pool of extended communities. The text in RFC5575 is ignoring this fact. The major implementations treat it as transitive. Fixed the reference Section 7.7/7.3
