Chapter 18: Checking the Status of Routing Tables
Checking OSPF Routing Status
CoreWatch can display the following information for OSPF routes that can be configured
through CLI commands:
• The OSPF interfaces configured on an SSR.
• The areas that the SSR can communicate with.
• The neighboring routers of an SSR.
• The link-state advertisements (LSAs) of the areas to which the SSR is attached.
An LSA is a packet that provides information about neighboring routers and
adjacencies to OSPF. The collected link-state advertisements of all routers and
networks forms the protocol's topological database. Routers use the information
included in link-state advertisements to update their routing tables.
• The IP address and TOS data that OSPF uses to determine the destination of packets.
Note:
For details on OSPF, see “A Look at OSPF Routing on the SSR” on page 345 .
Obtaining OSPF Interface Information
Obtain OSPF interface information if you want details about an SSR's OSPF interfaces. To
access this information, do one of the following:
• In the Front Panel view, select the Monitor menu, choose Routing State, choose OSPF
State
, and then choose OSPF Interface Table.
• In the Schematic view, double-click the OSPF Routing function.
An OSPF Interface table similar to the following appears:
