4.8.61 show ip ospf neighbor
This command displays information about OSPF neighbors. If you do not specify a neighbor IP address, the output
displays summary information in a table. If you specify an interface or tunnel, only the information for that interface
or tunnel displays. The
<ip-address> is the IP address of the neighbor, and when you specify this, detailed
information about the neighbor displays. The information below only displays if OSPF is enabled and the interface
has a neighbor.
If you do not specify an IP address, a table with the following columns displays for all neighbors or the neighbor
associated with the interface that you specify:
No Neighbor at
Source Address
The number of OSPF packets dropped because the sender is not an existing neighbor or the
sender’s IP address does not match the previously recorded IP address for that neighbor.
Note: Does not apply to Hellos.
Invalid OSPF
Packet Type
The number of OSPF packets discarded because the packet type field in the OSPF header is
not a known type.
Hellos Ignored The number of received Hello packets that were ignored by this router from the new neighbors
after the limit has been reached for the number of neighbors on an interface or on the system
as a whole.
