2 links between virtual chassis on Juniper EX4200

I have 2 virtual chassis with all ex4200 switcehs and currently they are connected with 1 link. What if I add another link between them. RSTP will shut the new link down. Correct? I need to configure integrated link to take advantage of 2Gbps link between the VC. Correct?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I think you're thinking about LACP

This allows for 2 or more ports to be bound...

But without the aggregated link, RSTP will shut the new link down. Correct?

Yes, if it is not (for example) configured in another (non-routed) VLAN, it will be blocked to prevent loops.
