We deployed a few Cisco 1000 Series Aggregation Services Routers across multiple data centers and office as high-performance edge and WAN aggregation routers. They serve as critical components for our services which we provide to our customers. We run full BGP feed from IP-Transits with RPKI, ROA and also connects to multiple IXs. We also run ACLs for secure and compliant edge routing.

Pros

MPLS traffic engineering and segment routing
Large-scale & redundant pathing using BGP/OSPF
ACLs for secure access control
RPKI

Cons

Commit & Rollback
Unified OS using IOS-XR just like ASR9K
ASR1006 should be calling 1004
Route-processor shouldn't be counting towards number of line card

Return on Investment

Improving deployment time
Enhancing network uptime and security requirements
Simplifying day-to-day operations and avoided significant downtime costs

Use Cases and Deployment Scope

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.

Pros

Very portable
Stable
Easy to config

Cons

Pricing

Return on Investment

Easy to implement

Alternatives Considered

Cisco 1000 Series Aggregation Services Routers (ASR 1000) and Cisco 9000 Series Aggregation Services Routers (ASR 9000)

Use Cases and Deployment Scope

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.

Pros

Open standard routing protocols (OSPF, BGP)
VRF Aware > allow us to segment each circuit per VRF instance.
Port density depending on the model and customer needs.
Easy to troubleshoot and configure.
Support for sub-interfaces using VLAN tagging which allows to separate traffic at the logical level.
High throughput.
Support for open standard LACP protocol and Cisco own PAGP protocol.
Route leak supported between VRFs.
Redundant PDUs.
Support for open standard AAA.

Cons

Security features
Take captures similarly to an ASA, it may get a little complicated to get the info needed.
A packet tracer feature that simulates how traffic will route across the router,
Better logging when traffic is getting dropped.

Most Important Features

VRF Aware capability
Open standard routing protocols.
Support for Dot1Q tagging
LACP support is definitely important.
Port density.

Return on Investment

We dont have invest in multiple routers(more than 30) to have 1 circuit per customer, this allowed us to build multiple environments and save money more than 30-50K in savings alone in this portion.
Licensing is done per set of features, this impacts in great way, given that we only need a couple of routers and a couple of licenses.
Device throughput support is really high, this allow us to honor customer circuit speed.

Use Cases and Deployment Scope

The ASR 1000 range is widely used by our different customers due to its good performance and a great variety of characteristics. They are easy to configure equipment. They can be used as WAN aggregation routers, enterprise network connectivity, We also use the routers as Internet gateways, as well as for organization MPLS network connectivity. in our client's services providers are widely used as RR

Pros

WAN aggregation router
MPLS
Excellent as Route Reflector
BGP routing externally and internally

Cons

Improve bandwidth throughput
Port density

Most Important Features

Enterprise services features
ZBFW
Highly reliable
Supports advanced encryption protocols
Quality of service
mpls

Return on Investment

The impact has been positive. ASR 1000 equipment as a WAN aggregation router, excellent equipment with MPLS feature, the negative side is that interface limited by 200G performance.

Use Cases and Deployment Scope

We have several ASR routers currently in our organization. We are using these routers not only as our internet routers, but also as our WAN routers in several of our branch offices. We rely heavily on these routers to perform well for our organization.

Pros

These routers are very good at performing 24x7! This is key to running an organization where employees are working 24x7.
The ZBFW feature works especially well to help lockdown and protect your network.
Having the ability to perform in-service upgrades is a key feature in keeping your network up at all times.

Cons

One room for improvement on these routers would be better QA testing on the software before it's released. We have had several IOS images that have had major bugs in them.

Most Important Features

The ZBFW (zone based firewall)
The 10 GB SFP ports
The ability to perform in-service upgrades

Return on Investment

We have been able to get a lot of life out of these routers, which is huge for our ROI.
A negative business impact would be when upgrading the router software and running into a bug in the software that causes downtime for our environment.
