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.
