backbone, but OSPF does not have a virtual link to the packet’s sender.

is not the area ID configured on the ingress interface.

destination IP address is not the address of the ingress interface and is not the AllDrRouters or
AllSpfRouters multicast addresses.

Wrong Authentication Type: The number of packets discarded because the authentication type
specified in the OSPF header does not match the authentication type configured on the ingress

existing neighbor or the sender’s IP address does not match the previously recorded IP address for
that neighbor.

not an existing neighbor or the sender’s address does not match the previously recorded IP address
for that neighbor.

system as a whole.

8.3.1.10 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.

Syntax

show ip ospf neighbor [interface <slot/port>] [<ip-address>]
