Monitoring Routing
You can use ASDM to monitor OSPF LSAs, OSPF and EIGRP neighbors, and the routing table. To
access the routing monitoring screens, go to Monitoring > Routing in the ASDM interface.
This section contains the following topics:
• Monitoring OSPF LSAs, page 43-1
• Monitoring OSPF Neighbors, page 43-5
• Monitoring EIGRP Neighbors, page 43-7
• Displaying Routes, page 43-8
Monitoring OSPF LSAs
You can view the LSAs stored in the security appliance OSPF database in the Monitoring > Routing >
OSPF LSAs area. There are 4 types of LSAs stored in the database, each with its own particular format.
The following briefly describes the LSA types:
• Router LSAs (Type 1 LSAs) describe the routers attached to a network.
• Network LSAs (Type 2 LSAs) describe the networks attached to an OSPF router.
• Summary LSAs (Type 3 and Type 4 LSAs) condense routing information at area borders.
• External LSAs (Type 5 and Type 7 LSAs) describe routes to external networks.
To learn more about the information displayed for each LSAs type, see the following:
• Type 1
• Type 2
• Type 3
• Type 4
• Type 5
• Type 7
Type 1
Type 1 LSAs are router link advertisements that are passed within an area by all OSPF routers. They
describe the router links to the network. Type 1 LSAs are only flooded within a particular area.
