  • 1.  AVI 22.1.6 + vCenter 7 inline load balancing

    Posted Apr 15, 2024 08:24 AM

    hi everyone, i have avi 22.1.6+ vcenter 7. I have already added vcenter as cloud and deployed Service Engines with virtual services on them.
    It is the working configuration for me now. And how i know it is called onearm mode.
    Configuration 1:
    Pool Member: 172.16.10.10
    VIP:172.16.10.9
    SE vNIC: 172.16.10.7-172.16.10.8

    But i want to segregate subnet for SE vNIC and set it for example 10.10.10.0/24
    Configuration 2:
    Pool Member: 172.16.10.10
    VIP:172.16.10.9
    SE vNIC: 10.10.10.1-10.10.10.10
    Is this scenario possible on AVI? I tried with different confugurations but every time, SE vnic gets ip address from the same subnet as it is pool member.

    Hi

    Reason this is happening is that the SE has access to the VLAN that the Server is connected on.

    The way to get around that is to create a Static Route that forces the connection via the new VLAN.

    In essence the static route will be: 

    Gateway - 172.16.10.10/32 or IP range if you have more than one server.
    Next Hop will be the Gateway for VLAN 10.10.10.0/24 which is possibly 10.10.10.1

    This will force it to use the 10.10.10.0 IP range to connect to the servers

    approximately i understand what you want to tell. I have tried multiple times, but there is not result. I have got:"Could not find host with reachability to networks"
    Is there any blogs similar to my deployment ?

    Does the VLAN 10.x.x.x exist with its relevant Portgroup?
    Did you create the Static Route on the VRF?
