OSPF Name Aggregation
Monitoring Network OSPF Name Activity
You can use the following techniques to examine the OSPF name database at the
switch level:
• Look at the local names field. This field is new with switch releases BSTDX
06.02.00.00, CBX 03.02.00.00, and GX 01.02.00.00, and greater. This field shows
the total number of OSPF names being advertised by the local switch.
• Look at the other new field, network names. This field displays the same
information as the sum of the existing name-LSAs
and name-summary LSAs
fields.
Viewing OSPF Names at the Switch Level
If you do not have the new fields in the switch code release you are running in your
network, you can still monitor OSPF name activity at the switch level. Use the
show
ospf names
command to view the entire OSPF name database in the network.
Running this command on the switch you are examining lets you view and count the
names that are associated with each switch. The following text is a sample excerpt
from the output for this console command.
You can use this command to determine the names that are associated with specific
switches. The highlighted field displays the entry 978/24 250.1/0, which means that
the OSPF name 978 (which has 24 bits) is being advertised by switch 250.1. A zero
appearing after the switch number means that a node prefix is used. A number other
than zero appearing after the switch number refers to the logical port interface index
(that is, it is a port prefix or port address).
