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 EMC 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 EMC 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 EMC Networking OS
Version 9.3(0.0), the number of hops to the ASBR for E2 routes are displayed in the output.
