BigIron RX# show ip ospf redistribute route

4.3.0.0 255.255.0.0 static

3.1.0.0 255.255.0.0 static

10.11.61.0 255.255.255.0 connected

4.1.0.0 255.255.0.0 static

In this example, four routes have been redistributed. Three of the routes were redistributed from
static IP routes and one route was redistributed from a directly connected IP route.

Syntax: show ip ospf redistribute route [<ip-addr> <ip-mask>]

The <ip-addr> <ip-mask> parameter specifies a network prefix and network mask. Here is an
example.

Displaying OSPF external link state Information

To display external link state information, enter the following command at any CLI level.

Syntax: show ip ospf database external-link-state [advertise <num>] | [extensive] | [link-state-id

<ip-addr>] | [router-id <ip-addr>] | [sequence-number <num(Hex)>] | [status <num>]

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.

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.

This display shows the following information.
