OSPF_1.3.6.1.2.1.14.16.2.10 ospfTxRetransmit

Description

An OSPF packet is retransmitted on a non-virtual interface. (RouterId=[RouterId], IfIpAddress=[IfIpAddress], AddressLessIf=[AddressLessIf], NbrIfIpAddress=[NbrIfIpAddress], NbrAddressLessIf=[NbrAddressLessIf], IfNeighbor=[IfNeighbor], PacketType=[PacketType], LsdbAreaId=[LsdbAreaId], LsdbType=[LsdbType], LsdbLsid=[LsdbLsid], LsdbRouterId=[LsdbRouterId])

An OSPF packet was retransmitted on a non-virtual interface because the physical link became faulty.

Impact on the System

When a packet is retransmitted on a non-virtual interface because the network is busy, this trap message will be generated, which leads to longer route synchronization and convergence.

Possible Causes

Cause 1: The IP address to which the packet will be forwarded could not be pinged.

Cause 2: The peer device determined that the packet was invalid.

Procedure

  1. Run the display ospf retrans-queue command to check the number of the retransmitted packets.

    • If only one or two packets are transmitted, go to step 5.
    • If a large number of packets are continuously retransmitted, go to step 2.

  2. Check the IP address of the neighbor where a packet is retransmitted, and run the ping command to check whether the link functions properly.

    • If the ping operation succeeds, go to step 3.
    • If the ping operation fails, go to step 4.

  3. Check whether the OSPF_1.3.6.1.2.1.14.16.2.8 ospfIfRxBadPacket alarm is generated on the local and peer devices. If the alarm is generated, locate the fault according to the trap message. If no such alarm is generated, go to step 4.
  4. Collect trap, log, and configuration information, and contact technical support personnel technical support personnel.
  5. End.
