Configure SEFOS1

1. Disable generation of a default external route.

   SEFOS# configure terminal
   SEFOS(config)# router ospf
   SEFOS(config-router)# no default-information originate always
   SEFOS(config-router)# end
   SEFOS#
   

2. Examine the results.

   Type 5 External LSA for the default route must be flushed.

   SEFOS# show ip ospf database external
    
   OSPF Router with ID (10.10.2.1)
   

3. In SEFOS2, observe that the route entry for the default route has been deleted.

   SEFOS# show ip ospf route
