Issue with Aggregated Ethernet (ae) interfaces in Juniper vLabs

    Hello everyone.

     I am trying to simulate ae interfaces in Juniper vLabs. I am running into an issue where the output of "show lacp interfaces ae0" shows the following. The ae interface is down.

    jcluser@PE25# run show lacp interfaces ae0  
    Aggregated interface: ae0
        LACP state:       Role   Exp   Def  Dist  Col  Syn  Aggr  Timeout  Activity
          ge-0/0/0       Actor    No   Yes    No   No   No   Yes     Fast    Active
          ge-0/0/0     Partner    No   Yes    No   No   No   Yes     Fast   Passive
          ge-0/0/2       Actor    No   Yes    No   No   No   Yes     Fast    Active
          ge-0/0/2     Partner    No   Yes    No   No   No   Yes     Fast   Passive
        LACP protocol:        Receive State  Transmit State          Mux State 
          ge-0/0/0                Defaulted   Fast periodic           Detached
          ge-0/0/2                Defaulted   Fast periodic           Detached


    The config is shown below.

    jcluser@CE41# show interfaces ge-0/0/0        
    gigether-options {
        802.3ad ae0;
    }
    
    [edit]
    jcluser@CE41# show interfaces ge-0/0/2    
    gigether-options {
        802.3ad ae0;
    }
    
    [edit]
    jcluser@CE41# show interfaces ae0 
    aggregated-ether-options {
        lacp {
            active;
            force-up;
        }
    }
    unit 0 {
        family inet {
            address 192.168.10.2/24;
        }
    }
    
    [edit]
    jcluser@CE41# show chassis aggregated-devices 
    ethernet {
        device-count 1;
    }
    


    When I use the force-up knob under ae0's [aggregated-ether-options lacp] hierarchy, ae0 comes up but only one interface is in "Collecting Distributing" state. 

    jcluser@CE41# run show lacp interfaces ae0 
    Aggregated interface: ae0
        LACP state:       Role   Exp   Def  Dist  Col  Syn  Aggr  Timeout  Activity
          ge-0/0/0 FUP    Actor  Yes    No   Yes  Yes  Yes   Yes     Fast    Active
          ge-0/0/0 FUP  Partner   No   Yes    No   No  Yes   Yes     Fast   Passive
          ge-0/0/2       Actor    No   Yes    No   No   No   Yes     Fast    Active
          ge-0/0/2     Partner    No   Yes    No   No   No   Yes     Fast   Passive
        LACP protocol:        Receive State  Transmit State          Mux State 
          ge-0/0/0 FUP              Current   Fast periodic Collecting distributing
          ge-0/0/2                Defaulted   Fast periodic           Detached


    I am not sure what I am missing. Is there some extra config that needs to take place, since this is the vLabs environment. 

    Looking forward to the guidance of community members. 
    Thanks in advance.
