Hi There. It seems you are trying to run LACP over a L2 service. Please keep in mind that LACP frames are native or untagged so therefore your switch will send LACP frames to the ISP as untagged. This means the ISP will need to transport the frame natively or will need to add a service tag on it and then transport it over the L2 service. If you want this working, you will need to have an access port to your ISP and then they can tag your LACP frame. The reason why your ae0 is down because of LACP in detached state. Some work arounds are you can create a physical loop on your switch and tag the traffic out to your ISP, you request your ISP to give you an access port or you can look at BFD if the interface is a routed interface on the switch.

Subject: 2 P2P Connection over EX4400 and Use it as Layer-2 Link between EX
In my case, I have 2 ISP connection between Junos devices.
First ISP
EX4400(ge-0/0/14)--------------------------------------------------JIO(ISP)---------------------------------------------(ge-1/0/14)EX4400
Second ISP
EX4400(ge-1/0/14)--------------------------------------------------Airtel(ISP)---------------------------------------------(ge-0/0/14)EX4400
If I am using any one link it is working fine, for using both link at same time, I created aggregated interface as per below configuration at both side switch.
set interface ge-1/0/14 ether-option 802.3ad ae101
set interface ge-0/0/14 ether-option 802.3ad ae101
set interface ae101 aggregated-ether-option lacp active
set interface ae101 unit 0 family ethernet switching interface-mode trunk
set interface ae101 unit 0 family ethernet switching vlan member all
But after that while I am checking interface terse of ae101, found physical link is up but ae101 is down.

Hi Suraj Singh,
I hope this example will help you.
https://supportportal.juniper.net/s/article/LACP-between-two-devices-with-a-transit-device-in-between-using-Layer2-Protocol-Tunneling?language=en_US
In this example ae0 interface configured as L3. You need use L2 configuration for ae0:
set interfaces ae0 unit 0 family ethernet-switching port-mode trunk
set interfaces ae0 unit 0 family ethernet-switching vlan members {all or list VLAN}
set interfaces ae0 aggregated-ether-options lacp active
set interfaces ae0 aggregated-ether-options lacp periodic fast

Hi IHOR SHTANKO,
I checked and found ISP provide me L2VPN Q-in-Q tunnel between my sites.

Hi Suraj,
A port aggregation (LAG) is not equivalent to a trunk. If your single port works fine as a trunk and you want to use a LAG instead of a single port, you need to configure a LAG on both sides of the connection, and then configure the trunk mode for that LAG.
Both links in the LAG work semultaniously. The traffice will be balanced between two links. What kind of P2P ISP connections do you have ( dark fiber or L2VPN)?
If you need active-backup solution you should use another solution.

Hi ALL,
I have two Point-2-Point ISP Connection between different location, at each location link is terminated on EX4400.
While we configured trunk at both side and pass all vlans, my all vlans of one location is working fine at another location, but while I am going to use aggregation port instead of trunk, my aggregation port is showing down while physical interface is UP.
at the same while I am checking mac or LLDP neighbor from either location it is not showing any LLDP neighbor also in LACP Interface output it is showing detached for that physical interface.
I have EX4400 with basic default license.
Is there any-one can help me on this, to extend my vlan from one location to another over ISP P2P link connected with EX4400 at the same time we can use second ISP link as redundancy.
Regards
Suraj Kant Singh
