Hi Deepak,
Both links will load balance traffic acting as a lag interface, below you can find more information,
https://www.juniper.net/documentation/en_US/junos/topics/concept/virtual-chassis-ex4200-aggregated-ethernet.html
You can configure optical uplink ports into Virtual Chassis ports (VCPs) that connect EX Series or QFX series switches together to form a Virtual Chassis. When you configure multiple uplink port VCPs connecting the same two member switches, those ports automatically form a LAG if the ports are configured to operate at the same link speeds. Each LAG is assigned a positive-integer identifier called a trunk ID. Up to 8 redundant VCP links can form a VCP LAG connecting two members in a Virtual Chassis, depending on the number of available ports that can be VCPs.
Please mark this post as Solved if this worked for you.
Regards,
Jeff

Subject: Load balancing across VCP links
Hi.
If I have two switches connected by two VCP links into a Virtual Chassis, will inter-switch traffic be forwarded across both VCP links or only one?
Thanks,
Deepak
