The
advertise
<num> parameter displays the hexadecimal data in the specified LSA packet. The <num>
parameter identifies the LSA packet by its position in the router’s External LSA table. To determine an LSA
packet’s position in the table, enter the
show ip ospf external-link-state
command to display the table. See
“Displaying the Data in an LSA” on page 20-47 for an example.
The
extensive
option displays the LSAs in decrypted format.
NOTE:
You cannot use the
extensive
option in combination with other display options. The entire database is
displayed.
The
link-state-id
<ip-addr> parameter displays the External LSAs for the LSA source specified by <IP-addr>.
The
router-id
<ip-addr> parameter shows the External LSAs for the specified OSPF router.
The
sequence-number
<num(Hex)> parameter displays the External LSA entries for the specified hexadecimal
LSA sequence number.
The
status
<num> option shows status information.
This display shows the following information.
Displaying OSPF Link State Information
To display link state information, enter the following command at any CLI level:
FESX424 Router> show ip ospf database link-state
Syntax:
show ip ospf database link-state [advertise <num>] | [asbr] | [extensive] | [link-state-id <ip-addr>] |
[network] | [nssa] | [opaque-area] | [router] | [router-id <ip-addr>] | [sequence-number <num(Hex)>] | [status
<num>] | [summary]
The
advertise
<num> parameter displays the hexadecimal data in the specified LSA packet. The <num>
parameter identifies the LSA packet by its position in the router’s External LSA table. To determine an LSA
packet’s position in the table, enter the
show ip ospf external-link-state
command to display the table. See
“Displaying the Data in an LSA” on page 20-47 for an example.
The
asbr
option shows ASBR information.
Table 20.6: CLI Display of OSPF External Link State Information
This Field...
Displays...
Area ID
The OSPF area the router is in.
Aging
The age of the LSA, in seconds.
LS ID
The ID of the link-state advertisement from which the Layer 3 Switch
learned this route.
Router
The router IP address.
Seq(hex)
The sequence number of the LSA. The OSPF neighbor that sent the
LSA stamps it with a sequence number to enable the Layer 3 Switch
and other OSPF routers to determine which LSA for a given route is
the most recent.
Chksum
A checksum for the LSA packet. The checksum is based on all the
fields in the packet except the age field. The Layer 3 Switch uses the
checksum to verify that the packet is not corrupted.
Type
The route type, which is always EXTR (external).
