Greetings,
If you use no ip split horizon, then you don't need to use neighbor command But if split horizon is on, you need to use neighbor command for it to adj.

V2 V1/2------| V1 In the network above, the V2 update will need to be communicated to the V1 only router. The V1/2 router will either have to disable split horizon and do a send version 1 2 or a neighbor command. In either case I am assuming we will need to disable split horizon - correct? Ajay Scott Morris <[EMAIL PROTECTED]> wrote: The "neighbor" command is a "more-specific" command which works separate from the "passive-interface" command. So if you have RIP on an interface and only use the neighbor command, you will get BOTH a multicast and a unicast packet on that interface. RIP allows you to do ONLY unicast by using both of those together. HTH, Scott Morris, CCIE4 (R&S/ISP-Dial/Security/Service Provider) #4713, JNCIE-M #153, JNCIS-ER, CISSP, et al.

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 ?
