IPv6 Commands
425
ProSafe Managed Switch

See show ip ospf interface stats on page 315 for a sample output of the number of OSPF

packets of each type sent and received on the interface.

show ipv6 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.

Format show ipv6 ospf neighbor [interface {<unit/slot/port> | tunnel
<tunnel_id>}][<ip-address>]
Modes • Privileged EXEC
• User EXEC
LSA Acks
Received The total number of LSA acknowledged from this interface.
LSA Acks Sent The total number of LSAs acknowledged to this interface.
Sent Packets The number of OSPF packets transmitted on the interface.
Received
Packets The number of valid OSPF packets received on the interface.
Discards The number of received OSPF packets discarded because of an error in the packet or an
error in processing the packet.
Bad Version The number of received OSPF packets whose version field in the OSPF header does not
match the version of the OSPF process handling the packet.
Virtual Link Not
Found The number of received OSPF packets discarded where the ingress interface is in a
non-backbone area and the OSPF header identifies the packet as belonging to the
backbone, but OSPF does not have a virtual link to the packet’s sender.
Area Mismatch The number of OSPF packets discarded because the area ID in the OSPF header is not
the area ID configured on the ingress interface.
Invalid
Destination
Address
The number of OSPF packets discarded because the packet’s destination IP address is
not the address of the ingress interface and is not the AllDrRouters or AllSpfRouters
multicast addresses.
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.
