options] >]
advertise: Displays the hexadecimal data in LSA packets
(advertisements) for the OSPF area(s) configured on the
routing switch. The output can also be filtered by area (area-
id), link-state-id, router-id, sequence-number, and/or type.
Default: All OSPF areas configured on the routing switch.
ospf-area-id: Used to restrict display of LSA database or
advertisements to show only the data from a specific OSPF
area. Can also be used with other subset options (router-id,
sequence-number, external link-state-id, and/or type) to further
define the source of displayed information.
link-state-id < ip-addr >
Used to restrict display of LSA database or advertisements
to show only the data from sources having the specified IP
address as a link-state ID. Can also be used with other
subset options (ospf-area-id, router-id, sequence-number,
external link-state-id, and type) to further define the source
of displayed information.
router-id < ip-addr >
Used to restrict display of LSA database or advertisements
to show only the data from sources having the specified
router ID. Can also be used with other subset options (ospf-
area-id, link-state-id, sequence-number, and type) to further
define the source of displayed information.
