Early Review of draft-ietf-i2rs-yang-l2-network-topology-02
I have been asked to provide a review to the following document to the
routing directorate mailing list.
Please be aware that this is the first time I work with YANG and related
Reviewer: Henning Rogge
Review Date: Mai 16th, 2016
Intended Status: Standards Track
The data structure suggested by the draft is reasonable and would fit
most Layer2 network technologies. I have a couple of points on the draft
document which might be worth looking into:
* The introduction in
includes a link to "I-D.ietf-netmod-rfc6020bis" that links back to the
draft document itself. Maybe some links in the document refer to an
older name of the draft?
* the "termination-point" element only contains the types "ethernet" and
"legacy" (which does not contain any data like mac-address). Is this
reasonable or should a few data elements moved from the "ethernet"
category to the "l2-termination-point-attributes" category?
* there are different types of VLAN tags be used... should there be
another field ("vlan-type" ?) to announce 802.1ad QinQ usage? I think
the 802.1ad tag is also sometimes also used to move VLAN over a switch
that doesn't support it (unknown Ethertypes are usually just ignored),
which means just knowing the VLAN-id is not enough to reach the endpoint.
* the type of ethernet (100, 1000, 10000) or data-rate could be an
important attribute for an ethernet termination point, not only for links.
