Spirent TestCenter: Why some of theOSPF adjacencies are stuck in Two Way and other are in Full states?

  • Spirent TestCenter.
  • OSPFv2.
If you have:
  • Different OSPFv2 devices under a single port.
  • All the devices are in the same network.
  • The OSPF network type is Broadcast.
When you start OSPF on the Spirent TestCenter Application, some of them will get stuck at the Two-Way status; this happens because having all the devices in the same network and the OSPF network type as Broadcast causes instability in the routing protocol.

There are a couple of things we can try to fix this problem:
  1. If you want to keep all the devices under the same port and network, you can configure the OSPF network type as P2P.
  2. If you want to keep the OSPF network type as Broadcast, you can configure each device under a different VLAN.
