The BGP sessions will flap after the RE switchover
Product-Group=evo
On all Junos and Junos OS Evolved platforms with dual RE (Routing Engine) or VC (Virtual Chassis) with NSR enabled scenarios, in some rare BGP scaled scenarios upon RE switchover the new Master RE will send out a route refresh message to all the peers, which is not expected. This will eventually lead to the BGP session flap.

The traffic for the same flow with the same tuple will be sent through different tunnels if the TTL value in IPv4 or the payload length in IPv6 is different
Product-Group=evo
On Junos OS Evolved QFX5130/QFX5700 platforms configured with EVPN-VXLAN (Ethernet VPN-Virtual Extensible LAN), when the packets of a flow have the same tuples but have different TTL (time-to-live) values or payload length, the packets will be sent through multiple VXLAN tunnels, which would lead to a jitter.

CCL:NGPR: filter with payload-protocol cannot be attached to the lo0 egress interface

The commit check 'filter with payload-protocol cannot be attached to the lo0 egress interface' was added to the 22.3 and onward releases as this feature was not supported by the Kernel. The same commit check was not added to 21.4 releases as adding this commit check was high risk. This commit check was introduced in the RLI 53437.

After the device reboots with lpm(longest prefix match) profile configured, the default route entry is getting created on ipv4 and ipv6 (pfe hw lpm) due to gRIBI routing instance and same route is removed after the interface flap.
Product-Group=evo
The multi-topology table gribi.inet6.0 is always created when the rib service is being instantiated. Since this is a dynamic table, if we do a configuration commit and the rpd infra module sees that the table is not being used, the dynamic table will be reclaimed (deleted) by the infra module. To prevent the rpd infra module from reclaiming the table, create a dummy route entry in gribi.inet6.0.
