Deleted BGP neighbors are still seen in Edge CLI but not on NSX GUI

Products

• VMware NSX

Issue/Introduction

• The BGP neighbors are deleted from the NSX GUI.
• These neighbors are not visible on the NSX GUI (Networking >Tier-0 Gateways > BGP > BGP Neighbors).
• From the NSX Edge CLI, these deleted neighbors are still seen and showing in "Active" state.

Example:

edge(tier0_sr[#])> get bgp neighbor summary
BFD States: NC - Not configured, DC - Disconnected
            DW - Down, IN - Init, UP - Up
BGP summary information for VRF default for address-family: ipv4Unicast
Router ID: 192.168.#.#  Local AS: 63###

• Rolling Reboot of NSX Manager nodes or associated Edge nodes do not resolve the issue.
• Stale alarms associated with these deleted BGP neighbors, such as "BGP Down", may still be seen in the NSX GUI.
