This needs to be in both te-topology model and te model. Will bring the topic to TE model discussion meeting. > Agreed to add underlay TE path for each connectivity-matrix entry. - Make LLCL entry as rich as connectivity entry, to have enough TE information for path computation. > Xufeng to prepare the model change proposal. - Have a list of attributes to be used for technology specific augmentations. > Dieter to prepare the list for the meeting after Dieter is back from vacation. - Schedule down time (in addition to up time) | +--rw schedules | | +--rw schedule* [schedule-id] | | +--rw schedule-id uint32 + | | +--rw inclusive-exclusive? enumeration | | +--rw start? yang:date-and-time | | +--rw schedule-duration? string | | +--rw repeat-interval? string + leaf inclusive-exclusive { + type enumeration { + enum inclusive { + description "The schedule element is inclusive."; + } + enum exclusive { + description "The schedule element is exclusive."; + } + } + description + "Whether the list item is inclusive or exclusive."; + } - info-source: bgp-ls leaf information-source { type enumeration { enum "unknown" { description "The source is unknown."; } enum "locally-configured" { description "Configured entity."; } enum "ospfv2" { description "OSPFv2."; } enum "ospfv3" { description "OSPFv3."; } enum "isis" { description "ISIS."; } + enum "bgp-ls" { + description "BGP-LS."; + reference + "RFC7752: North-Bound Distribution of Link-State and + Traffic Engineering (TE) Information Using BGP"; + } enum "system-processed" { description "System processed entity."; } enum "other" { description "Other source."; } } description "Indicates the source of the information."; } - Clean up notifications We currently have notifications for te-node and te-link. These notifications are covered by draft-ietf-netconf-yang-push and draft-gonzalez-netconf-5277bis. We will remove these notifications from te-topology model. - Need to complete counters/statistics. Each of us will think about what attributes are needed. > number of operational links/tunnels > number of recoverying links/tunnels > number of protection switches > number of protection reversions Thanks, - Xufeng Note: Please drop me an email if you need an invite for joining the weekly call.
