Cisco ISR 1000 Series for FTTP Line 1000/50

[ST-IOS]

Hi all,

Context: Just signed up to a new NBN service with Launtel 1000/50 looking for a Cisco ISR with relatively low noise to use as a home router. I want a ISR that can run at or close to the line speed.

Just had a question in regards to the ISR 1100 series, does any router support 1Gb through-put? I have been looking at a Cisco ISR 1100 (C1121X-8PLTEP ).

Platform performance

Ref: Cisco 1000 Series Integrated Services Routers Data Sheet - Cisco

Table 17.     Cisco 112x ISR Controller Mode (SD-WAN) performance specifications – 17.9 Release (Bidirectional)

Feature	C112x(X)-8P	C112x-4P
SD-WAN IPsec throughput (1400 bytes)	1889 Mbps	1426 Mbps
SD-WAN IPsec throughput (IMIX)	465 Mbps	338 Mbps
SD-WAN overlay tunnels	200	200

Thanks

According to the Data Sheet (Table 18), an 1121 can support up to 1673 Mbps (non-SDWAN).  

For NBN use, this is fine.  Do take extra steps to lock down the router, particularly put ACLs in place to keep unwanted IP addresses from discovering the router.
