OSPF/4/VINTF_NSR_OVERTIME_LIMIT: The virtual link interface go on process, as slave's ack didn't come for [ULONG] seconds. (NbrID=[STRING], IpAddr=[IPADDR], ProcessId=[USHORT], TransitAreaId=[STRING])
If the OSPF virtual interface on the active board receives no response from the standby board within a specified interval, the active board considers that the standby board has responded and does not require retransmission of backup messages.
| Parameter Name | Parameter Meaning |
|---|---|
| [ULONG] | Total time that the virtual interface waits for the response from the standby board, in seconds |
| NbrID | Name of the virtual interface |
| IpAddr | IP address of the virtual interface |
| ProcessId | Process ID to which the virtual interface belongs |
| TransitAreaId | Area ID to which the virtual interface belongs |
After the virtual interface on the active board initiates a handshake with the standby board, the interface waits for a response from the standby board. If the total waiting time exceeds the upper limit (equal to or less than 600 seconds, generally 40 times of the retransmission interval), it may be caused by inconsistent OSPF interface statuses on the active board and the standby board, blocked backup channel, or loss of backup messages.
