RE: Redistribute a RIP default route into OSPF

Jose,

Actually, it is not possible to redistribute any default into OSPF, AFAIK.
If there is a default in the forwarding table that you want to go into OSPF,
then you would use the "default-information originate" command. With this
command it is not necessary to do a "redistribution" command, and if you
redistribute without "default-inf originate", then the redistribution will
not work.
