Subject: [trill] AD review of draft-ietf-trill-multilevel-unique-nickname-03

 

As is traditional, I have done my AD review of draft-ietf-trill-multilevel-unique-nickname-03.  First, I would like to thank the authors - Margaret, Donald, Mingui, and Dacheng - as well as the reviewers and shepherd, Sue, for their work on this document.

 

I do have some minor comments, but these can be addressed ASAP while the draft is in IETF Last Call.  I will request that to start and place this on the IESG telechat on March 8.

 

 

Minor:

 

a) In Sec 3.1, it says " 

      1) RB27 and RB3 have learned that D is connected to nickname 44.

      2) RB27 has learned that nickname 44 is accessible through RB3."  

 

    Given that RB2 is the local area's Level Border Router, I think that is RB2 not RB3. Granted, RB3 needs to know also - but that is info from its local area.

 

b) In Sec 4.3:

" For nicknames in these ranges, other RBridges will deem that they are owned by the originating border RBridge. The paths to nicknames that fall in these ranges will be calculated to reach the originating border RBridge. TRILL Data packets with egress nicknames that are neither in these ranges nor announced by any RBridge in the area MUST be discarded. " 

 

I think this only applies if OK = 0 - and that needs to be restated as part of the condition.

 

Regards,

Alia
