Obtaining OSPF Area Aggregate Information
Obtain OSPF area aggregate information if you want details about the IP address and TOS
data that OSPF uses to determine the destination of packets. To access this information:
1.
If you are not in the Front Panel view, switch to it by clicking the CoreWatch main
window.
2.
Select the
Monitor
menu, choose
Routing State
, choose
OSPF State
, and then choose
OSPF Area Aggregate Table
.
An
OSPF Area Aggregate
table similar to the following figure appears:
Sequence
Indicates the sequence number of the link-state advertisement.
This field is used to detect old and duplicate link state
advertisements.
The larger the number the more recent the link-state
advertisement.
LS Age
Indicates how old the link-state advertisement is. The value in
this field is given in seconds.
Checksum
Indicates the checksum of the complete contents of the link-
state advertisement, except for the age field. The age field is
excluded so that a link-state advertisement’s age can be
incremented without updating the checksum.
LS DB Advertisement
Contains the entire link-state advertisement including its
header.
