@qiluo-msft I didn't find a YANG table for BGP_INTERNAL_NEIGHBOR nor BGP_VOQ_CHASSIS_NEIGHBOR. I need to know the fields under these tables so I can double check if they are create-only or not.

@ganglyu These tables are missing yang models and also minigraph parsing/validation unit test.

I have created above issues to trace this requirement, and I will discuss with BGP owner and Multi-asic team to add these Yang models.

Please refer to above link, it seems that BGP_INTERNAL_NEIGHBOR and BGP_VOQ_CHASSIS_NEIGHBOR are similar, and the fields under these tables are: name, local_addr, rrclient, holdtime, keepalive, nhopself, admin_status and asn.

[GCU] Marking fields under BGP_PEER_RANGE, BGP_MONITORS as create-only (
2c56e92 
#2092)

#### What I did
Fixes #2029 #2062

Changes to fields under BGP_PEER_RANGE, BGP_MONITORS using GCU are not reflected unless each key is deleted and added back. This means the fields are create-only.

#### How I did it
Marked the fields under BGP_PEER_RANGE, BGP_MONITORS as create-only

#### How to verify it
unit-test
