The cosmetic error messages of NTP time synchronization might be seen during device booting
In NTP with the boot-server scenario, when the router or switch boots, the NTP daemon will send a ntpdate request to poll the configured NTP boot-server to determine the local date and time. If the ntpdate is not be activated correctly while the device booting, the ntpdate might not work successfully. Then some cosmetic error messages of time synchronization might be seen, but there is no impact with time update since ntp daemon will update the time eventually.

Dvaita JDM:The emitted XML is INVALID is thrown for show virtual-network-functions
Issue: XML output for the cli operational command 'show virtual-network-functions' is invalid as the xml data contains all the VNF info under single root tag 'vnf-instance' However this issue doesn't lead to any JDM functionality break. It can be considered as an issue only if this xml output is consumed by any XML parser and the parser doesn't expect the duplicate tags for multiple vnfs under a single root tag, but when it expects the each vnf information as a group.

UID may not release properly in some scenarious after service session deactivation
When same UID objects are used in both inet and inet6 services of the same subscriber session, deactivation the first session cause conditions which avoid releasing UID entry after deactivation second service session. This leads to having stale UID entry and can cause subscriber's connection problem in the future when UID pool would be completely exhausted. The probability of hitting the issue increases if amount subscriber to amount of unique services ratio is aproaching 1 (i.e. when almost every subscriber has a service with unique servie objects).

This PR includes three issues. First one: When Layer3 IFL (logical interface) is configured first and then Layer2 IFL is configured, MAC move might not happen. Second one: On Vxlan setup with large number of child interfaces, link up delay is seen. Third one: In case of VLAN setup with Enterprise/Service Provider L2 and L3 type configs, when all the configs are done in single commit statement then the traffic might not be forwarded.

Routes resolution might be inconsistent if any route resolving over the multipath route
On all Junos platforms, any route resolving over the multipath routes, one scenario is BGP over BGP. After the metric value of any PNH (refers to the second PNH and using it to performing the second time next-hop resolving) changes, meanwhile, if the hash-selection changes happened, it might result in routes resolution inconsistency. Traffic drops could be observed if the packages are still forwarding to the old PNH (Protocol Next Hop). Any recursive resolving multipath scenario might trigger this issue.
