BGP routes might be left stale on the router
Product-Group=evo
On all Junos and Junos Evolved platforms, if the BGP peer goes down, and the very last route in the list is marked as a high priority, BGP might assume no more routes to delete, causing routes to be stale.

Traffic blackholing is observed when removing the BGP routes take a long time to get removed from RIB
Product-Group=evo
On Junos platforms, if a BGP (Border Gateway Protocol) peer is going down and stays down and the system might take an extremely long time to complete removing the BGP routes. The issue observed when a BGP peer sends many routes, only a small amount of routes are selected as the active routes in the RIB (Routing Information Base), and if the BGP delete job gets only a small part of the CPU time as other work in the routing process utilize the CPU.

The l2ld process will crash when an IFL is changed to trunk mode and a new VLAN is added
Product-Group=evo
On all Junos Evolved platforms, the Layer 2 address learning daemon (l2ald) process will crash when there is a scaled configuration to commit and a Logical Interface (IFL) mode is changed from access to the trunk and a new Virtual Local Area Network (VLAN) is added to the IFL in a single commit. This issue will impact new MAC learning until the l2ald process recovers.

The BFD fails to come up when RE filter is configured with apply-path
Product-Group=evo
On Junos OS Evolved platforms, the Bidirectional Forwarding Detection (BFD) protocol will fail to come up. This happens when the Routing Engine (RE) filter is applied with the filter term having source-prefix-list derived from apply-path configured with - "interfaces <*> aggregated-ether-options bfd-liveness-detection neighbor". The issue occured in the commit handling after correcting the apply-path string.

On all Junos and Junos Evolved platforms supporting preference-based DF (Designated Forwarder) election in EVPN-MPLS Multihoming scenario, the DF election will be stuck in the Preference based state if there will be a change in the df-election on the fly.

Traffic loop is seen due to incorrect root bridge ID
Product-Group=evo
On all Junos and Junos Evolved platforms, in VSTP (Virtual Spanning-Tree Protocol) topology, whenever a new vlan is added in between previously configured vlan group followed by configuring the system-identifier, the bridge priority will change for existing vlans which might give incorrect system ID or bridge ID creating a traffic loop.

OSPF routes are not getting installed after the interface is flapped
Product-Group=evo
On all Junos and Junos Evolved platforms, the OSPF (Open Shortest Path First) routes are not getting installed when the interface is flapped multiple times. A deadlock is created when the OSPF routers wait for an LSA (Link State Advertisement) with a P2P (Point-to-Point) link to be advertised from its neighbouring router to add it to its router LSA and at the same time the neighbouring router also waits for an LSA with a P2P link to be advertised to add it to its router LSA. Both the OSPF routers advertise their router LSA without a P2P link and as a result, routes are not getting installed.
