General Routing

  • Egress IP MTU exception and fragmentation are not supported. PR1558327

  • High CPU seen mostly with systemd with 4000 mac-vrf instances activate or deactivate. PR1581283

  • PICD restart or crash might result in junk statistics for carrier transition. PR1594253

  • Default CoS profiles applied to Layer 2 VPN and Layer 2 circuit logical interfaces are not shown in the output of run show class-of-service-interface IF. PR1596342
