Hi draft-ietf-opsawg-sap-09 authors

I have several comment regarding the draft.

Since I don't see a placeholder for configuration object that can be configured in the service attachment point. I believe it would be better to enrich the SAP model with the popular attachment circuit configuration of l2vpn and l3vpn, such as:

  *   Multicast protocol like IGMP(snooping), MLD(snooping)
  *   DHCP (snooping)
  *   IP/mac filter
  *   QOS policy
  *   OAM
  *   IP address
  *   Some extra fields can be reserved for arbitrarily usage

The use case that I can think of is when a Controller wanna config a service with L2NM or L3NM the following path can be augmented with the detail of SAP model


  *   /l3nm:l3vpn-ntw/l3nm:vpn-services/l3nm:vpn-service/l3nm:vpn-nodes/l3nm:vpn-node/l3nm:vpn-network-accesses
  *   /l2vpn-ntw:l2vpn-ntw/l2vpn-ntw:vpn-services/l2vpn-ntw:vpn-service/l2vpn-ntw:vpn-nodes/l2vpn-ntw:vpn-node/l2vpn-ntw:vpn-network-accesses

Similar can also for the service configuration retrieval.


Cheers/Asad
