For 4.3/4.4, I’m guessing this is the same solution. For 4.5, here’s a couple of options we could implement:
1. New isolation provider (“BrocadeVLAN” or “JuniperEXVLAN”) 2. When creating the network offering, the administrator gets to select the guru 3. New VLAN provider mechanism.

Thanks Chiradeep and Murali for the reply! I am thinking of explicitly telling ExternalNetworkGuru to skip design when Brocade plugin is designing the network. I don't want to disable ExternalNetworkGuru from default build when Brocade plugin is not present so won't exclude it from the spring class loader.

This is know design issue. Unlike service orchestration (which has prescriptive way to tell which network elements to be called for with network offerings ) there is no such logic for network design. Orchestrator just loops through all the network guru's asking to design the network which can results in one or more networks. Hugo did a cleanup [1] but I believe it was not merged as there was no consensus. There is 1-1 mapping between isolation type and Guru but In this case both Brocade Guru and ExternalNetworkGuru will attempt to design the VLAN isolated networks. One in-elegent solution is to hard code ExternalGuestNetworu guru to skip network deign when Brocade plug-in is supposed to do design the network. Other option could be exclude ExternalNetworkGuru bean from spring class loader.

That is strange. Looks like a bug to me. That is because the ExternalGuestNetworkGuru returns 'true' for canHandle.

Hi, I am writing a Network Guru for automatically orchestrating Brocade VDX switches to provide tenant isolation via VLAN. In my NetworkGuru, I have implemented the canHandle() method for Guest isolated network in Advanced zone using VLAN isolation. When the NetworkOrchestrator selects the NetworkGuru, it selects my NetworkGuru and the ExternalGuestNetworkGuru also and I see 2 networks created. How do I make sure that ExternalGuestNetworkGuru is not selected by NetworkOrchestrator. Thanks & Regards, Ritu S.
