BIG-IP is failing to reach the default gateway.

We are facing problem in reaching the default gateway from one of the partition we create on BIG IP system (vCMP Guest on vCMP host BIG-IP5200v Chassis), we have create a vlan with /26 subnet, it has a two local ip address (one on each unit) and a floating address. The DG is a SVI on the a juniper firewall and the transit is built on a nexus 5K switch, the set-up is like; BIG-IP (vCMP Guest) >> LCAP (multiple vlans)>>> Nexus layer 2 >>LCAP (multiple vlans)>>> Firewall. Note: • We have around more than 20 vlans on the LCAP and all working good except the new vlan we have created. • I could see the mac address on firewall interface on the layer switch but I couldn’t find the BIG-IP’s Interface (New VLAN) MAC. Please advice, thank you.

You must present the VLAN to the guest from the hypervisor, otherwise it would not work.

Please refer to a screenshot from our hypervisor on how to present the VLAN:

  1. Logon to the hypervisor
  2. Click on guest list
  3. Choose the guest you want to present the vlan to
  4. Move the VLAN from available to selected
  5. Done

Does the switch log a lot of discards by any chance?

  • Have you configured the VLAN in the hypervisor?
  • Have you added it to the existing trunk in the hypervisor?
  • Have you presented the VLAN to the guest from the hypervisor?

Hi Patrick,

Thank you, please see my response below;

Does the switch log a lot of discards by any chance? There aren't any message on the switch. Have you configured the VLAN in the hypervisor? Yes Have you added it to the existing trunk in the hypervisor? We created the vlans on the vCMP Guest Have you presented the VLAN to the guest from the hypervisor? i did on the vCMP guest directly.
