Hi everybody,
just as an information. I got massive issues with BGP sessions on NSX-v edge gateways in version 6.4.6.
It looks like that BGP session informations kills the routing service.
Here a screenshot of my edges (left 6.4.6 edge with the issue, right 6.4.5 edge working fine)
Query all neighbour infos, then query routing infos for a specific neighbour. Next query shows that all BGP sessions are reset.
Doing multiple cli querys in a short time kills the routing - service completly.
Also doing no query will kill the routing service after a while.
I have a scheduled a session with VMware support today regarding this issue.
Please be careful if planning to upgrade you NSX-v to 6.4.6
