Re: pls help, easy ospf question

more correct config is
network 0.0.0.0 255.255.255.255 area X
because 255.255.255.255 is expected to be wildcard.

on new IOS(on most IOS), when you enter in router ospf
network 0.0.0.0 0.0.0.0 area X
it will be automagicaly converted, and saved in config as
network 0.0.0.0 255.255.255.255 area X

so no mistake here.

i'd recommend to lear some debug commands, such as debug ip ospf
packets and debug ip ospf hello. using this command check why
adjacencies are not forming.
