Reference Guide
– ge min-prefix-length: is the minimum prefix length to match (from 0 to 32).
– le max-prefix-length: is the maximum prefix length to match (from 0 to 32).
For configuration information about prefix lists, refer to Access Control Lists (ACLs).
Redistributing Routes
You can add routes from other routing instances or protocols to the OSPF process.
With the redistribute command, you can include RIP, static, or directly connected routes in the OSPF
process.
NOTE: Do not route iBGP routes to OSPF unless there are route-maps associated with the OSPF
redistribution.
To redistribute routes, use the following command.
• Specify which routes are redistributed into OSPF process.
CONFIG-ROUTEROSPF-id mode
redistribute {bgp | connected | isis | rip | static} [metric metric-value |
metric-type type-value] [route-map map-name] [tag tag-value]
Configure the following required and optional parameters:
– bgp, connected, isis, rip, static: enter one of the keywords to redistribute those
routes.
– metric metric-value: the range is from 0 to 4294967295.
– metric-type metric-type: 1 for OSPF external route type 1. 2 for OSPF external route type 2.
– route-map map-name: enter a name of a configured route map.
– tag tag-value: the range is from 0 to 4294967295.
Example of Viewing OSPF Configuration after Redistributing Routes
To view the current OSPF configuration, use the show running-config ospf command in EXEC
mode or the
show config command in ROUTER OSPF mode.

Troubleshooting OSPFv2
Dell Networking OS has several tools to make troubleshooting easier.
Be sure to check the following, as these questions represent typical issues that interrupt an OSPFv2
process.
NOTE: The following is not a comprehensive list, just some examples of typical troubleshooting
checks.
• Have you enabled OSPF globally?
• Is the OSPF process active on the interface?
• Are adjacencies established correctly?
• Are the interfaces configured for Layer 3 correctly?
