Dear authors,
I have a number of questions regarding this L2 topology YANG.
1. Does draft-ietf-i2rs-yang-l2-network-topology support the modelling of a
termination point that maps to a VLAN sub-interface?
This capability would facilitate the creation of a topology stack for the
following use cases:
* Mapping a ietf-l3-topology TP over a vlan sub-interface
In this case a TP in ietf-l3-topology instance would be supported by a VLAN
sub-interface TP in the l2-topology
* Mapping different VLAN IDs in a L2 ports to different services
i. For
example, on a particular L2 port, VLAN 23 might be an attachment circuit for
VPLS #78, where as VLAN 99 might be an attachment circuit for L3VPN #999
If draft-ietf-i2rs-yang-l2-network-topology does not have the capability to
model VLAN sub-interface as a TP, is there a different way for
draft-ietf-i2rs-yang-l2-network-topology to support the above use cases?
1. The VLAN sub-interface YANG
(https://tools.ietf.org/pdf/draft-ietf-netmod-sub-intf-vlan-model-06.pdf) being
developed has some overlap with draft-ietf-i2rs-yang-l2-network-topology. It
would be good if there would be better alignment between the two:
* Use similar definition/fields where possible; even better use shared
grouping definition
i. For
example outer-tag and inner-tag
* VLAN sub-interface YANG
(https://tools.ietf.org/pdf/draft-ietf-netmod-sub-intf-vlan-model-06.pdf)
flexible encapsulation supports symmetric and asymmetric rewrites, which does
not appear to be supported by draft-ietf-i2rs-yang-l2-network-topology.
1. Consider the scenario where a domain controller implementing
draft-ietf-i2rs-yang-l2-network-topology is also implementing schema mounted
ietf-interface to model the interface stacks of the managed devices:
* Is there a mechanism in draft-ietf-i2rs-yang-l2-network-topology to
associate a L2 TP with the corresponding interface entry in the schema mounted
ietf-interface?
1. For a LAG link, would the LAG TP be expected to be also represented by
/nw:networks/nw:network/nw:node:termination-point/tp-id/supporting-termination-point
to its membership TPs?
It would be useful to clarify for uniform implementation across different
vendors.
Thank you.
Warm regards,
