## Test SEFOS1

1. Test the redistribution configuration.
   1. Type.

          SEFOS# configure terminal
          SEFOS(config)# router ospf

   2. Configure redistribution of the static route's redistribution configuration.

          SEFOS(config-router)# redistribute static

   3. Configure the redistribution configuration.

          SEFOS(config-router)# redist-config 20.0.0.0 255.0.0.0 metric-value 100 metric-type asExttype1 tag 10
          SEFOS(config-router)# exit

   4. Add a static route for the `20.0.0.0/8` network.

          SEFOS(config)# ip route 20.0.0.0 255.0.0.0 10.4.0.2
          SEFOS(config)# end
          SEFOS#

   5. Examine the configuration details.

      An external LSA is generated for `20.0.0.0` with metric as 100, metric type as `asExtType1` and tag as 10.

          SEFOS# show ip ospf database external

          OSPF Router with ID (10.10.2.1)
                            AS External Link States

          Forward Address    : 10.4.0.2
          Externel Route Tag : 10

2. In SEFOS2, examine the external route `20.0.0.0/8` with metric as 101.

       SEFOS# show ip ospf route

3. In SEFOS1, test no `redist-config`.

       SEFOS# configure terminal
       SEFOS(config)# router ospf

4. In SEFOS1, configure the switch to have no redistribution configuration.

       SEFOS(config-router)# no redist-config 20.0.0.0 255.0.0.0
       SEFOS(config-router)# end
       SEFOS#

5. In SEFOS1, examine the configuration details.

   The external LSA generated for `20.0.0.0` with metric as 100, metric type as `asExtType1`, and tag as 10, is flushed. A new external LSA is generated with the default redistribution configuration.

       SEFOS# show ip ospf database external
