Giving the command "Passive-interface Default" or atleast "Passive-interface [Interface connected to Switch ]" is important on Router C & B apart from "Neighbor" command. Passive command will stop sending updates [Only Receive] by default on the interface Neighbor will send Unicast Updates. So in conclusion A will not get any updates but B & C will have each others Plus A's networks in their routing table.

Date: Sun, 16 Aug 2009 23:34:05 +0000 Hey, Being connected to a switch makes no difference. On B and C you are only sending routes to each other and ONLY each other. The network statement on A only tells A to advertise the networks out an interface. It will not receive any routes though.

But Routers A , B and C are connected to Switch also. Router A Configrouter ripnetwork 172.16.10.0 Router B configrouter ripnetwork 172.16.10.0neighbor 172.16.10.3passive-interface se0/2 Router C configrouter ripnetwork 172.16.10.0neighbor 172.16.10.2passive-interface se0/3 Now We have network command 172.16.10.0 at A as well on C. won't they share routes ? Please note they are connected to Switch. I am not sure .. but I will do this in lab. once I reach home.

No A would not receive routes. How would it if you are only unicasting between B and C? Regards, Joe Astorino - CCIE #24347 R&S Technical Instructor - IPexpert, Inc..

Initially A B and C were sending updates to each other via broadcasts. Now if I will use unicast (neighbor + passive interface + network command) on B and C , still A will receive updates right , because A is already configured with network command , please advise ?
