The use of the explicit neighbor command will still follow split horizon rules 
- is that correct?

            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?

 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.

Subject: [OSL | CCIE_RS] RIP neighbor  clearification


 
 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 ?
