Cisco ASA Series CLI Configuration Guide
Chapter 1 Configuring OSPF
Monitoring OSPF
Monitoring OSPF
You can display specific statistics such as the contents of IP routing tables, caches, and databases. You
can also use the information provided to determine resource utilization and solve network problems. You
can also display information about node reachability and discover the routing path that your device
packets are taking through the network.
To monitor or display various OSPFv2 routing statistics, enter one of the following commands:
Command
Purpose
show ospf
[
process-id
[
area-id
]]
Displays general information about OSPFv2
routing processes.
show ospf border-routers
Displays the internal OSPFv2 routing table entries
to the ABR and ASBR.
show ospf
[
process-id
[
area-id
]]
database
Displays lists of information related to the OSPFv2
database for a specific router.
show ospf flood-list
if-name
Displays a list of LSAs waiting to be flooded over
an interface (to observe OSPF v2packet pacing).
OSPFv2 update packets are automatically paced so
they are not sent less than 33 milliseconds apart.
Without pacing, some update packets could get lost
in situations where the link is slow, a neighbor
could not receive the updates quickly enough, or
the router could run out of buffer space. For
example, without pacing, packets might be
dropped if either of the following topologies exist:
•
A fast router is connected to a slower router
over a point-to-point link.
•
During flooding, several neighbors send
updates to a single router at the same time.
Pacing is also used between resends to increase
efficiency and minimize lost retransmissions. You
also can display the LSAs waiting to be sent out of
an interface. Pacing enables OSPFv2 update and
retransmission packets to be sent more efficiently.
There are no configuration tasks for this feature; it
occurs automatically.
show ospf interface
[
if_name
]
Displays OSPFv2-related interface information.
show ospf neighbor
[
interface-name
]
[
neighbor-id
] [
detail
]
Displays OSPFv2 neighbor information on a
per-interface basis.
show ospf request-list
neighbor
if_name
Displays a list of all LSAs requested by a router.
show ospf retransmission-list
neighbor
if_name
Displays a list of all LSAs waiting to be resent.
show ospf
[
process-id
]
summary-address
Displays a list of all summary address
redistribution information configured under an
OSPFv2 process.
