[j-nsp] EX4200 Virtual Chassis Uplink Requirements - Extended VCT / VCCP

[Doug Hanks]

The MX implementation of VCCP uses standard 802.1Q with a vlan-id of 4094.
 I'm sure the EX is the same as well.  The maximum latency is 100ms.

Although I agree having a virtual chassis span a WAN isn't the best idea
ever.

Thank you,
