Re: [v6ops] Continuing WGLC: ietf-v6ops-dhcp-pd-per-device-03

[Joel Halpern <[e-mail]>]

Having re-read the draft, I consider that it is ready for publication as 
an Informational RFC.   Two minor comments that may be considered for 
inclusion are noted below.

Minor:

     In section 4(Design Principles) bullet 4, it refers to 
communicating with other devices as per RFC 7084 WAA-7.  However, when I 
go read WAA-7, I can't connect the dots.  Is there a typo in the 
reference?  Or is there a subtlety that should be better explained?

   It may make sense to add a sentence noting that intermediate relay 
routers do not need to snoop DHCP responses, as the leaf relay router is 
expected to inject the delegated prefix into the routing system.  
Snooping is only require, if I read this properly, for the first-hop 
relay routers.

Yours,

Joel
