Cisco 1000 Series Aggregation Services Routers (ASR 1000)

ASR 1000 are used as network Route reflectors in key places in the network and as PE for client aggregation where it is not justified to install bigger routers like ASR 9k or Nexus 8k.

The Cisco 1000 Series Aggregation Services Routers (ASR 1000) are deployed as Internet Routers and also as WAN Routers that connect remote offices to the HQ. It is able to support high network bandwidth with ease to scale to support higher bandwidth throughout by the use of add-on licenses. Cisco 1000 Series Aggregation Services Routers (ASR 1000) are also easy to use, configure, and it can troubleshoot should the need arise.

As MPLS PE routers.
The scaling of the box is the main issue.

I used Cisco 1000 Series Aggregation Services Routers (ASR 1000) for BNG usage in previous work. The scope was an old infrastructure upgrade for a small ISP (about eight thousand subscribers). It responds to all needs I expect for PPP / L2TP termination. This product was a great alternative for old Cisco 7200 routers.

We use it in our Business partner network zone, we connect multiple customer own circuits here, it is great for port density and private cloud environment where multi tenancy is required, the device is VRF aware and supports a variety of routing protocols (Open standard), which allow us to peer with the providers or customers. This device is ideal for WAN, it has multiple models, but it surely performs properly.
