F5 using mgmt ip to communicate to the back end servers on the range of the mgmt vlan

Hello,

 

I have F5 with 5 Vlans ( 4 vlans to communicate to the back end servers ) and the fifth vlan for VIPs and I have separated mgmt on differnt vlans

 

suppose these vlans to make the question clear: vlan 10,11,12,13 to communicate to back end servers vlan 14 for VIPs vlan 15 for mgmt IP

 

the issue is, F5 is using the mgmt ip to communicate to the back end servers on the same range of the mgmt

 

example: if I have back end server on vlan 15 , F5 using mgmt ip ( which on the same vlan ) to communicate to the back end server

 

I have default route only on the VIP vlan ( vlan 14 ).

 

mgmt vlan should be seperated and not engaged on the traffic

 

could you support on that

    You need to keep your management network on a separate subnet - are you able to provide config examples for the management and TMM IP configurations? Feel free to obfuscate any information that may be sensitive.
