Cisco 1000 Series Aggregation Services Routers (ASR 1000) vs. Cisco Routers

Based on my past and current experiences as a network engineer, they serve and run really well and also simplify our setup where we used them as edge or border or internet gateway routers. And also we used them as Data Center Interconnect, terminating dark fibers using LR or ZR SFP+. Even though they are well suited for enterprise network, there may still be some room for improvement with SRv6.

Cisco Routers, particularly ASRs, are well suited at the edge or perimeter of your network topology since they're capable of aggregating large data and performing fast packet processing. To be even more specific, they are great at handling full internet BGP route tables and aggregating multiple WAN connections. Some scenarios where they may be less appropriate might be for much smaller sites running less critical services that may not need "state of the art" enterprise routers.

• 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.

• Helps to separate routing information for different networks for different customers.
• Helps peers with service providers and Customer Networks and starts the exchange of information between them.
• Helps facilitate internet connectivity for enterprise networks.
• Helps transferring Internet or Private Data from one place to another.

• The ASR 1000 series routers can, as with most devices, improve with additional memory capacity and upgraded chip sets for faster processing.
• There seems to be limitations on the number of routing sessions the smaller ASR devices can handle, which can be overcome with proper planning and placement within the network.

Incentivized

• It will be helpful if configuration can be done using a http GUI
• Graphical Visualizing provisioned VPN services will helps in troubleshooting
• Software upgrade process should have an automated way, that helps in managing large no of devices in the network

The device without a doubts performs at the level required and expected, we can renew it and use it as we have been using it for years. The device can be used as DCI, IPN/ISN, or even private cloud for customer circuit handoff, it also supports IPSec properly. The device is well suited in multiple segments of the network.

We are extremely likely to renew, as we have been very happy with our Cisco Routers for over 10 years. Their uptime as well as stable nature makes them ideal for us, as we are an industry that cannot afford downtime. We trust our partner to recommend our next model Cisco, when the time comes.

All our modular contingency service exercises use this equipment, it allows us to perform this type of exercises very easily, in a controlled and effective way. It is used at least once a month for these types of events. It also allows configuration replication in computers that are under the same model.

The best thing about Cisco products is their presence in community. When you have a problem you can do quick search and find whoever else had the same question and expert answer for that question. Other thing is there are Cisco certified people we can find very easily if want some help with comissioning these products

Incentivized

We have received training on the equipment, which has made us add more networks on our own, we provide first level support, we validate the publication of the equipment and we can satisfy the needs of our internal clients in terms of the prompt recovery of the affected services

Cisco support is very good. Of course, sometime you will run into support guy that isn't up to the task. Buf overall, the support system is well structure. You know if this support isn't able to help, you can esclate the situation to find another help. Also, their documentation is well developed and can be very useful.

Implementation was as per design and all best practice configuration was followed.

We haven't used any other manufacturer other than Cisco. [H]owever, we have used different models that Cisco offers. The ASR has a little more horsepower than the ISR. Both are very good routers though.

Other vendors definitely bring some great features. We've gone from Fortinet to HPE, to Ruckus. Each product has benefits to consider. For us, Cisco is a trusted brand that's used about thousands of customers and many fortune companies. While some of the newer or smaller players have great features, Cisco has most of the same plus time in the trenches.

• It is a healthy return on investment with planned packed size data. Average unicast latency is low and consistent with small and large packets (barring mid-sized).
• Cisco devices last longer and also have a decent trade-in policy to recover some value when equipment is replaced.
• Higher concurrent IPSec tunnels are offered, we tested for 1500+, fielding both encrypted and a mix of encrypted and cleartext traffic.

Incentivized

• Network management has become easy and fast with cloud based portal.
• Network policies could be rolled out quickly across the devices.
• Improvement in Network security.
• Stable internet connection has lead to less downtime and more productivity.
• Stable internet connection in each location within the organization.
