Is is posible to do something similar to Cisco Cross-Stack Etherchannel on pair of EX4200 switches as core and couple of EX2200 access switches?If so, can someone provide me link for detailed documentation.
Hi m0ps in junos this is called an mc-lag, and unfortunately mc-lag is not available on EX switches. You can do a lag between ports on different members of a virtual chassis, but today no MC-LAG is available on any EX product line. Just the MX product line.
First of all - thanks for your reply acooley. It's not a good news. Mainly, i think to use Cross-Stack Etherchannel for core high avaibility. Is there another solution to do a core with pair of EX4200 and couple of EX2200 access switches higly avaible?
Maybe there is a whitepaper with reference architecture for small campus from Juniper?
hey m0ps, a virtual-chassis gives you all the h/a you could mostly want, there were some limitations with code upgrades on older revs, but that is roughly coming to an end. So ultimately have a multi unit chassis cluster I think will give you everything you want, just put more then 1 switch in a VC, and setup a lag between ports inside the VC.
Another option would be to use an MX which does have support for mc-lag, but the EX team didn't implement this because VCs are the way they want folks to go for inter-chassis redundancy.
It would be good for you to reach out to your SE and discuss this with them, do you know who your local sales rep and SE are?
