Hi I am actually confused in usage of passive-int and neighbor command in case of RIP . I understand that if we use passive-interface for a given interface ; UPDATES will not be sent out that interface .
The only usage that i can think of "neighbor" command is that on a broadcast network where we want non-broadcast exchange of routing info . i.e if we wanna establish rip relationship between particular rtrts ; then we can use it .. is there some other usage ?? actually am confused by usage given in CCO which says : router rip network 10.108.0.0 passive-interface ethernet 1 neighbor 10.108.20.4 *In the above case ; if neighbor 10.108.20.4 is located out eth 1 .. still no RIP update will go to that router .. right ?* Gaurav Madan.
