Usage
Information
To isolate problems with external routes, use this command. In OSPF, external routes are calculated by
adding the LSA cost to the cost of reaching the ASBR router. If an external route does not have the
correct cost, use this command to determine if the path to the originating router is correct. The display
output is not sorted in any order.
NOTE: ASBRs that are not in directly connected areas are also displayed.
You can determine if an ASBR is in a directly connected area (or not) by the flags. For ASBRs in a directly
connected area, E flags are set. In the following example, router 1.1.1.1 is in a directly connected area since
the Flag is E/-/-/. For remote ASBRs, the E flag is clear (-/-/-/).
Example
DellEMC# show ip ospf 1asbr
RouterID Flags Cost Nexthop Interface Area
3.3.3.3 -/-/-/ 2 10.0.0.2 Te 1/1/1/1 1
1.1.1.1 E/-/-/ 0 0.0.0.0 - 0
DellEMC#
show ip ospf database
Display all LSA information. If you do not enable OSPF on the switch, no output is generated.
Syntax
show ip ospf process-id [vrf vrf-name] database [database-summary]
Parameters
process-id Enter the OSPF Process ID to show a specific process. If no Process ID is entered,
command applies only to the first OSPF process.
vrf vrf-name Enter the keyword vrf and then the name of the VRF to view LSA information on
OSPF processes corresponding to that VRF.
