    OSPF vs EIGRP:  will network 0.0.0.0 cause the advertisement of a default route?

    Vincent Ricci

      Question:  Will IOS advertise a default route 0.0.0.0/0 into the OSPF domain when using the command network 0.0.0.0 255.255.255.255 area 0

      (as EIGRP does when using network 0.0.0.0) ?

       

      In EIGRP, network 0.0.0.0 will cause IOS to *** put a default route *** into the EIGRP table (Route 642-920 page 128).

       

      In OSPF, I am not sure...  and I want to confirm that IOS behaves differently (or not)...

       

      I know OSPF router sub-commands redistribute {static | bgp} or default-information originate  would advertise 0.0.0.0/0 (flood LSA-type 5 or -7/nssa)

      But I want to know specifically about network 0.0.0.0 255.255.255.255.area 0 and confirm any specific difference/similarity with EIGRP.

       

      Thanks!
