Command depends on routing protocol. You are probably in EIGRP. 'default-information originate' is used with OSPF and ISIS. As we found out recently, newer versions of IOS allow this command under RIP as well, although I have to wonder what that does as RIP advertises the default route without it anyway (after redistribution, of course).
