Cisco 1000 Series Aggregation Services Routers (ASR 1000) vs. Cisco 500 Series WPAN Industrial Routers (IR 500)

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.

• 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.

• 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.

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.

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.

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

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.

• 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.
