I just had the same conundrum - although I needed gigabit. Mine was between ASR1k and an ASR920. I had a requirement for netflow - and although on the roadmap - I couldn't get a date out of cisco for the feature release on the 920. I needed netflow from day1. The chaps here gave me lots of info on the 920 - and It seemed perfect apart from this.
Also with the 4xxx series ISR - remember that the 43xx is like 3xxx ISR but running XE - i.e very software based. The 45xx series is far more similar to the ASR1k as many more features are done in hardware. I however have only used the 4451 to terminate VTi and DMVPN, with QOS and it has performed like a champ. However for the 920 VS ASR1k - I bought the ASR in the end. -----Original Message----- From: cisco-nsp [mailto:cisco-nsp-boun...@puck.nether.net] On Behalf Of Michael Malitsky Sent: 22 September 2015 01:53 To: cisco-nsp@puck.nether.net Subject: [c-nsp] ASR920 vs ISR4000 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.
