Hi Jonathan, thanks for the reply.

The application is a service provider edge, all ethernet, with routed
traffic to two carriers.  Internal traffic is a mix of IGP and OSPF.

I'll have to take a look at the EX series.  All of the literature on
the juniper site suggests the EX is targeted more toward lan
aggregation while the SRX handles the edge.

Thank you!
