This task describes how to configure dynamic routing using the redistribution feature of the OSPF protocol in SEFOS. This task verifies that the reachability between two hosts is established after learning the in-between routes dynamically through OSPF.
See Routing Feature Topology for the topology of this task.
See Configure Static Unicast Route Entries.
The basic VLAN configuration for dynamic routing is similar to the basic VLAN configuration for static routing. If the configuration information was not saved on SEFOS-1 and SEFOS-2, follow Step 1 through Step 6 in Configure Static Unicast Route Entries.
If SEFOS-1 or SEFOS-2 is a third-party switch, configure the basic VLAN and the dynamic routing as recommended by the switch's manufacturer.
SEFOS-1# configure terminal SEFOS-1(config)# router ospf SEFOS-1(config-router)# asBR router SEFOS-1(config-router)# router-id 10.0.0.201 SEFOS-1(config-router)# network 20.0.0.201 area 0.0.0.0 SEFOS-1(config-router)# network 10.0.0.201 area 0.0.0.0 SEFOS-1(config-router)# redistribute all SEFOS-1(config-router)# end
SEFOS-2# configure terminal SEFOS-2(config)# router ospf SEFOS-2(config-router)# asBR router SEFOS-2(config-router)# router-id 40.0.0.200 SEFOS-2(config-router)# network 20.0.0.200 area 0.0.0.0 SEFOS-2(config-router)# network 40.0.0.200 area 0.0.0.0 SEFOS-2(config-router)# redistribute all SEFOS-2(config-router)# end
If SEFOS-2 is a third-party switch, verify that the OSPF protocol is enabled on SEFOS-2 and that related configurations are applied accordingly.

If SEFOS-2 is a third-party switch, use the appropriate command to verify the neighbor router status.
