The layer 3 throughputs listed should be any issue for the EX switches. You
will be limited to about 10k routes.

You'll need to be on the 4200 platform to do virtual chassis.

Hi there..


Does anyone have any real-world feedback on the layer3 performance of EX3200
and/or EX4200 switches?  I've searched around and cannot find out the
capabilities (pps/Gbps) but new to the Juniper world ;)


Our needs are reasonable simple I think - considering putting in 10 EX4200
in a virtual chassis configuration using the Virtual Chassis Cabling.  This
allows us ample copper ports on the front and we can use the 4X1GE or 2X10GE
ports for our fiber needs.  Total layer3 throughput would probably be about
1Gb/s average and peak at 2Gb/s.  OSPF, some small ACL, and IPv6 would be


Thanks for any feedback,
