Trying Active-Active-Standby in LAB, 2 devices show as offline.

Hey Gents,

This was the plan:

BIGIP1-A TG1
BIGIP2-A TG2
BIGIP3-S For both TG1 and TG2

But right now all TGs are only ACTIVE on BIGIP3 and shows as "Initializing / Not Synced".

On BIGIP3 I did tmsh list cm device unicast address

root@(bigip3)(cfg-sync In Sync)(Active)(/Common)(tmos) list cm  device unicast-address
cm device bigip1.akm.com {
    unicast-address {
        {
            effective-ip 192.168.20.50
            effective-port cap
            ip 192.168.20.50
            port cap
        }
        {
            effective-ip 10.128.1.243
            effective-port cap
            ip 10.128.1.243
            port cap
        }
    }
}
cm device bigip2.akm.com {
    unicast-address {
        {
            effective-ip 192.168.20.51
            effective-port cap
            ip 192.168.20.51
            port cap
        }
        {
            effective-ip 10.128.1.244
            effective-port cap
            ip 10.128.1.244
            port cap
        }
    }
}
cm device bigip3.akm.com {
    unicast-address none
}

Since its's all a lab, here are the QKVIEWs on gdrive for all 3 devices.

Thanks a ton for the help!

    What are the unicast network failover ip addresses on bigip3.akm.com??

     

    Cheers,

    First make sure each device in the Device Group has the following configured correctly,

    • Configsync Ip
    • Mirroring IP
    • Failover Unitcast IP/Multicast IP

    Once corrected ensure each device has the other 2 devices listed correctly and as connected under 

    Device Management  ››  Device Trust : Peer List

    You may need to delete and redo the Trusts to ensure all three trust each other and see each other as connected.

    If you run 

    show cm device
    you should see something like this:

    -----------------------------------------------------------------
CentMgmt::Device: f5vm01.test.lab
-----------------------------------------------------------------
Hostname                        f5vm01.test.lab

    Then setup your traffic groups, one at a time, 

    show cm traffic-group traffic-group-1 traffic-group-2
    should look like this:

    -------------------------------------------------------------------
CM::Traffic-Group
Name             Device                 Status   Next
                                                 Active
-------------------------------------------------------------------
traffic-group-1  f5vm01.test.lab        active   false
traffic-group-1  f5vm02.test.lab        standby  false
traffic-group-1  f5vm03.test.lab        standby  true

traffic-group-2  f5vm01.test.lab        standby  false
traffic-group-2  f5vm02.test.lab        active   false
traffic-group-2  f5vm03.test.lab        standby  true
