Hello Experts,
I am newbie to Juniper world. 
I have a question about setting up a HA parir SRX cluster.
I have planning to do a setup like this. First thing I wanted to know is whether this is a valid design?
The reason why I am aiming for etherchannel between SRX and the switch is there a around 10 differnet zones that we need to setup in SRX. I could set each zone into a physical interface in SRX. What I wanted to check is if there is way to setup a trunk from switch to SRX and push differnet zone traffic to SRX. At the same time I need to setup differnet Reth interfaces for all zones for HA between the SRXs.
To recap the requirements are:
1) All 10 zones traffic sent to the SRX using a Etherchannel that carries different VLAN traffic to SRX
2) Have a proper HA cluster using Reth interfaces for 10 different redundancy groups.
Please let me know if you need more details.
