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 typevalue] [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. DellEMC(conf-router_ospf)#show config ! router ospf 34 network 10.1.2.32 0.0.0.255 area 2.2.2.2 network 10.1.3.24 0.0.0.255 area 3.3.3.3 distribute-list dilling in DellEMC(conf-router_ospf)# Troubleshooting OSPFv2 Use the information in this section to troubleshoot OSPFv2 operation on the switch. Be sure to check the following, as these questions represent typical issues that interrupt an OSPFv2 process. NOTE: The following tasks are not a comprehensive; they provide 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? • Is the router in the correct area type? • Have the routes been included in the OSPF database? • Have the OSPF routes been included in the routing table (not just the OSPF database)? Some useful troubleshooting commands are: • show interfaces • show protocols • debug IP OSPF events and/or packets • show neighbors • show routes To help troubleshoot OSPFv2, use the following commands. • View the summary of all OSPF process IDs enables on the router.
