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 prexes; 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.
