Major		Multicast packets are getting dropped when multicast is configured in strict-ordering mode
Product-Group=junos		On Junos OS SRX1600 platforms, when multicast is configured in strict-ordering mode, and certain threads are dedicated to processing multicast traffic, some multicast packets get dropped. This occurs due to the way the system handles message processing in this configuration, which can impact multicast traffic forwarding.

Major		Crash in the rpd process after LDP P2MP LSP Identifier reaches its maximum value and rolls over, due to duplicate identifier allocation
Product-Group=junos		On all Junos OS and Junos OS Evolved versions that support Label Distribution Protocol Point-to-Multipoint Label Switched Paths (LDP P2MP LSPs), the rpd process (routing protocol daemon) crashes when an LSP Identifier reaches its 24-bit maximum value (224 1 = 16, 777, 215) and rolls over to the starting value because a duplicate identifier is incorrectly allocated. This condition occurs only after prolonged tunnel flapping (typically more than 16 million flaps). When the rpd process crashes, routing convergence is briefly disrupted, and services relying on label-switched traffic are impacted until the process automatically restarts.

Major		MVPN Source PE might incorrectly send mcast traffic on SPT while actual receiver is still on RPTree
Product-Group=junos		In currently flow when a provider tunnel is being deleted, it is assumed the cmcast routes associated to the ptnl would've have been updated before. This is fine for inclusive tunnels, however for selective tunnels especially wild card scenarios the cmcast routes may not be updated. So in cases where the ptnl is deleted like configuration based removal or underlying tunnel going down, there is chance that the forwarding routes are still not deleted. The cmcasts are deleted later in the flow but when they are deleted the corresponding forwarding routes are still not deleted since there is no corresponding ptnl for the cmcast. This will create issues if forwarding is supposed to happen via different forwarding entry like a *, G entry but since the more specific S, G stale entry exists, traffic will hit the later and lead to unexpected behavior like traffic black-holing if S, G is Pruned entry.

Product-Group=junos		An LSI IFL remains in RPD even after being deleted by the interface manager daemon. It is visible in show interface routing but not in show interfaces, indicating that RPD still holds the IFL despite its removal elsewhere. rpd-agent does not send a delete message to RPD due to a reference count issue. Another daemon?likely l2ald?still holds a reference to the IFL. rpd-agent only sends the delete once all references are cleared, which doesn't happen in this case. The fix is to send a "delete pending" message from rpd-agent to RPD. RPD will treat this as a delete and remove the IFL, ensuring consistency across the system.
