Hi All,
I am having a problem with OSPF neighbors stuck in the state of INIT. I am currently running a point to multipoint network. The core of the network has a Cisco 6509 installed and at each remote site either a cisco 3750x or a cisco C3560CG 8 Port switch is installed.

Hello,
check if VTP pruning is enabled on the switch, and if so, disable it (no vtp pruning).

Hello,
set the 6509 to VTP mode server and the 3560 to VTP mode client.

Make sure both the side switches are VTP Transparent and VLAN available locally and SVI up and running. Do you have reachability between 20.200.201.242 to 200 10.200.202.1 on both the side
i saw the message was OSPF area 200 ? what is the other side area configured?
can you below the device not working
show version
from both the side
show run interface vlan 700
show run | begin router ospf
show ip route

I am not clear whether this is an implementation that has worked and then stopped working or if it is a new deployment which has not ever worked. If it has worked and stopped, were changes made? Has there been some event that might have impacted the network? In either case is there any possibility of MTU mismatch between neighbors?
