(OSPF)
receiveError
Number of general receive errors.
Interpretation:
■
A non-zero value indicates that OSPF packets are being
dropped and that this could be causing routing problems.
This statistic is incremented under the following circumstances:
■
When an OSPF Hello packet is received and the packet
length is too short.
■
When an OSPF Hello packet is received that has the same
router ID as the router receiving the packet.
■
When an OSPF database descriptor packet is received and
the packet length is too short.
■
When an OSPF link state request (LSR) packet is received and
the packet length is too short.
■
When processing an LSR packet, if the area is not
configured on the interface.
■
When an OSPF link state update (LSU) packet is received and
the packet length is too short.
■
When processing an LSU packet, if there are more than 500
advertisements the packet is not processed.
■
When an OSPF link state acknowledgement (LSAck) packet
is received and the packet length is too short.
■
When processing an LSAck packet, if the area described by
the packet is not known by the router receiving the packet.
■
When processing any OSPF packet, if the packet length is
less than the OSPF header length then it must have been
truncated and the packet is dropped.
■
When an OSPF packet is received on an interface that is not
running OSPF.
■
When an OSPF packet is received over a virtual link, but the
virtual link is down or not configured.
■
When an OSPF packet is received (over a non-virtual link)
from a source whose IP network does not match the IP
network of the interface on which it was received.
■
When an OSPF packet is received on a Non-Broadcast
Multiple Access network from an unknown neighbor.
■
When an OSPF packet is received whose version is not OSPF
version 2.
