routing from vlan to different ospf stub area

hi all,

attached my topology.

i need some way, to propagate network 200.0.0.0/24 resides on the middle switch on vlan 200.

the network showld be propagate to all ospf stub areas, so that routers that not directly connected will know how to reach it.

currently their is 0.0.0.0 0.0.0.0 area X command under the router ospf 1 process.

so the ospf advertised all his vlans and connected interfaces.

in the other hand, i need to add decision mechanism (like static route), to forwerd traffic to the currect site.

please advise.

thanks in advance.

This is OSPF configuration guide

basically, if I undestand correctly, this is waht you need on the middle router

"network

area "

under "router ospf " command,

where

is your network to propogate

and

area stub [no-summary] on stub routers

Hi,

   Please explain a bit more about your design. Seems you have 2 OSPF domains. So site A and  site B cannot reach each other. Right? Do you want to propagate 200.0.0.0/24 network  to site A and site B. Right? Can you run the routing protocol on the switch connected to vlan 200?
