I'm new to virtual chassis and I do not understand some subjects in the mixedmode section ..
- Which switchs models I can connect in mixed mode VC ?
- Is there any minimum / maximum number of FPCs in mixedmode VC ?
A fairly detailed coverage of this topic can be found here: http://www.juniper.net/techpubs/en_US/junos16.1/topics/concept/virtual-chassis-ex-qfx-series-mixed-u...
As to the limits, there are two routing-engines and up to 8 line cards in pretty much any VC.
