[c-nsp] ASR920 vs ISR4000

[Chuck Church]

Unless your QOS requires shaping, it seems like an L3 switch like a 3560
would work.

I need to upgrade the edge router for one of my deployments.  Current 2811
is not expected to support the new WAN links.  I need 4-5 ports (copper is
fine), aggregate throughput up to 125Mb (not accounting for future growth),
BGP with 3-5 peers and <100 routes, and QoS.  I don't ever expect to support
telephony or MPLS.  Cisco's suggestion is to use an ISR4331.

The question is whether I should also consider an ASR920 for this role?
I've seen it mentioned on this list a few times.  It looks like both will
fill my basic requirements, price points are similar, and both run IOS-XE.
The ISR's performance is capped at 300Mb, and I can add a small number of
ports.  The ASR's performance is essentially unlimited, and I can add more
ports (by purchasing licenses).  The ISR will do encryption if I ever need
it, in software only, and the ASR will not.

Are there any major differences I am missing?  Any first-hand experiences
would be especially appreciated.

Sincerely,
Michael
