# GEN AD review of draft-ietf-bess-evpn-pref-df-11

CC @larseggert

Thanks to Vijay Gurbani for the General Area Review Team (Gen-ART) review
(https://mailarchive.ietf.org/arch/msg/gen-art/yyKue3u0e4F2LuAMSzjlxaEKHrQ).

## Comments

### Section 1.1, paragraph 2
```
     While the Default Designated Forwarder Algorithm [RFC7432] or the
     Highest Random Weight algorithm (HRW) [RFC8584] provide an efficient
     and automated way of selecting the Designated Forwarder across
     different Ethernet Tags in the Ethernet Segment, there are some use-
     cases where a more 'deterministic' and user-controlled method is
     required.  At the same time, Service Providers require an easy way to
```
Why is "deterministic" in quotes here? Is this algorithm not
(always) in fact deterministic? Could a more accurate term be
chosen?
[Jorge] I removed “deterministic”. I think “user-controlled method” conveys the meaning that we want in this text.


### Section 4.1, paragraph 1
```
     Assuming the operator wants to control - in a flexible way - what PE
     becomes the Designated Forwarder for a given virtual Ethernet Segment
     and the order in which the PEs become Designated Forwarder in case of
     multiple failures, the following procedure may be used:
```
It's not clear what kind of procedure the list items a-f describe. The
individual list items read more like standalone considerations than
any kind of procedure.
[Jorge] we changed the first paragraph, hopefully it reads better now. Let us know please.


## Nits

All comments below are about very minor potential issues that you may choose to
address in some way - or ignore - as you see fit. Some were flagged by
automated tools (via https://github.com/larseggert/ietf-reviewtool), so there
will likely be some false positives. There is no need to let me know what you
did with these suggestions.
[Jorge] ok, thanks.

### Outdated references

Document references `draft-ietf-bess-evpn-virtual-eth-segment-11`, but `-12` is
the latest available revision.
[Jorge] updated, thanks.

### Grammar/style

#### Section 4.1, paragraph 3
```

                                   ^^^^^

#### Section 4.1, paragraph 4

#### Section 4.3, paragraph 19
```

Did you mean "different from"? "Different than" is often considered colloquial
style.
[Jorge] fixed
