Usage
Information
This command is useful in isolating routing problems between the OSPF and the RTM. For example, if a
route is missing from the RTM/FIB but is visible from the display output of this command, the problem is
with downloading the route to the RTM.
This command has the following limitations:
● The display output is sorted by prefixes; intra-area ECMP routes are not displayed together.
● For Type 2 external routes, Type 1 cost is not displayed.
NOTE: Starting with Version 9.4(0.0), the loopback IP address advertised to the neighbor is not
displayed in the output because they are not accounted as inactive OSPF routes, whereas the
loopback IP address is displayed until Dell Networking OS Version 9.3(0.0). Starting with Version
9.4(0.0), the show ip ospf routes command displays the interface and area ID information of
connected networks in addition to the other settings, whereas these details are not displayed until
Dell Networking OS Version 9.3(0.0). Starting with Version 9.4(0.0), the metric of E2 routes in the
output is displayed as an external metric, whereas until Dell Networking OS Version 9.3(0.0), the
number of hops to the ASBR for E2 routes are displayed in the output.

show ip ospf statistics
Display OSPF statistics.
Syntax
show ip ospf [process-id | vrf vrf-name] statistics global | [interface
name {neighbor router-id}]
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 followed by the name of the VRF to display statistics
corresponding to the OSPF process that is tied to a specific VRF.
global Enter the keyword global to display the packet counts received on all running
OSPF interfaces and packet counts OSPF neighbors receive and transmit.
