So if you use rip ver 2 with no-autosummary configure and under the f0/0 interface issue the "ip rip send send ver 1" something like this with out using interface command "ip summary-address rip", would it advertise summary or classfull network out the the peer if the peer has both ver 1 and ver 2 capability?
