OSPF issue? - Page 2 - Alcatel Unleashed
I get this result if I detach 1/1 on cc (or 1/2 on omni10.10.100.1), is OK because on omni10.10.100.1:1 171 ms 2 ms 2 ms 10.10.100.1

There are not the same networks 10 or 20(vlan-10,vlan-20), but transit networks vlan-14/vlan-15 and vlan-24/vlan-25, you yourself have configured. It is all Layer3! And these we don't blocked with ACLs.I saw "show ip route" from yours config and in your case preferred gateways on the network 10, so can you please connect additional pc to the network 20 on 10.20.100.1switch, make this pc 10.20.100.201 and try to do "traceroute" to 10.30.112.201 pc. I'm pretty sure that all traffic gonna go through 10 network...

simply put corresponding transfer ip networks to appropriate network groups.Network 10.10.x.x has to communicate through 10.10.250.x network and network 10.20.x.x has to communicate through 10.20.250.x network, that's it.
What exactly do you mean by RING. I just modified your configuration so that it works, no vlans added or removed. I see 2 cabling rings in your visio picture, but in your configs these all are separate transit networks (mask /30). The same is with vlan-10 and vlan-20, there are all have separate networks on each switch. Therefore I always thought that you mean Layer 3 configuration on all switches(OSPF). But if you are saying these RINGs are Layer 2, then your design is wrong and you need to define where is L3 and where is L2.Don't forget that this is RING topology.
