General Routing

  • The ping command might show variable latency values. This is an expected behavior for host generated ICMP traffic due to the design of the Packet Forwarding Engine queue polling the packets from ASIC. PR1380145

  • The circuit-cross-connect logs do not compress after rotation. PR1398511

  • In a race condition, if a BGP route is resolved over the same prefix protocol next hop in a routing table that has routes of the prefix from different routing protocols, when the routes are flapping (firstly these routes are down and then up), the BGP route will be resolved again, and then the rpd process might crash. PR1458595

  • On ACX710 routers with the console cable is plugged in, if the terminal connection is active and sending characters to the interface, the system boot might be interrupted and the boot will be stalled at the uboot# prompt. PR1513553

  • On ACX710 routers, alarm does not raise while booting the system with the recovery snapshot. PR1517221

  • On ACX5448 routers, ping stops working even though the ARP entry is present during continuous script executions. PR1533513

  • In MC-LAG, interchassis link (ICL) interface needs to be configured as an aggregated Ethernet interface. Multicast traffic looping might be occur if other interfaces are configured. PR1567790

  • On ACX448 routers, while bringing up CFM session with SLM or DM iterator profile, failed allocating packet buffer messages were seen in the Packet Forwarding Engine intermittently. This results in failure of the CFM session activation or only failure messages were seen sometime. There is no functionality impact due to this error message. PR1574754

  • On ACX5448 routers, the micro BFD session with VLAN-tagging gets stuck in the Init state. PR1574780

  • On ACX5448 routers with a Layer 3 VPN scenario, after multiple core link flaps, the following error message might be seen: dnx_nh_unilist_install_multipath: Failed to create shadow obj 0x20017ff0 for NH 766(FEC 0x2000109f) unilist nh 2097161. Error -14(No resources for operation). PR1621425
