Hi
I thought cross chassis lag is supposed by the use of reth bundled at SRX end. I read this is basically the major difference in reth Vs ae bundle in SRX. Interesting factor here is that ae bundles can spread across multiple EX chassis in a virtual chassis environment but this cannot be the case with ae bundles in SRX. Thanks.
