Overall Satisfaction with Cisco Routers
- Cisco ASR 1000 Series
- Cisco ASR 9000 Series
Our Cisco Routers are being used accross our organization at multiple sites. While they typically serve the function of a reliable and "bulletproof" internet edge router, they can also handle a robust QoS workload. This had been especially useful at some of our sites that have firewalls deployed at the edge that are only capable of supporting a limited number of QoS classes. The ASRs gives us the flexibility of extending our QoS requirements (where QoS'ing closer to the source is not possible) with very minimal limitations.
Pros
- ASRs do a phenomenal job of handling large routing tables
- Fast packet processing
- Aggregating multiple WAN connections
- Handling large flows of traffic
Cons
- I think there should be a bit more QA and testing done on new image releases. Some of the images released within the last couple years had more bugs than I expected. Thankfully, some of the bugs were just cosmetic in nature but could still confuse network engineers when troubleshooting certain issues.
- Due to their reliability, they've provided high uptimes for our sites and venues (which is critical during events)
- They've been able to handle full internet BGP tables without breaking a sweat. At peak times in our business, they easily forward large aggregate amounts of data without a hiccup.
- If you're troubleshooting at the edge, on your ASR, that can often mean you're troubleshooting a critical issue. This means that time is of the essence. Using Cisco IOS XE on the ASRs is a pleasure. Everything is snappy, to the point, and the output is very informational.
Not quite. It wasn't necessarily a "compatibility" consideration with other Cisco devices in our organization, but more so familiarity with the Cisco IOS as most of our engineers are very well versed with Cisco. Also, while there are plenty of other more cost effective options (such as Juniper), several of us have supported ASRs at other organizations and we collectively agreed that they are the most reliable edge routers we've ever worked with.
We have. We have leveraged AAA services on our ASRs, VRF lite, and zone based firewalls in the past. Another example is utilizing features like AS path filtering or no export communities to prevent our AS from becoming a transit AS.
Cisco routers have always been the most reliable and stable devices I've used in comparison to other vendors routers. They also have the best TAC support which is something that we always evaluate when purchasing critical equipment positioned in critical segments of our network.
Cisco Routers are the most reliable and stable internet edge routers ive used. They' have also always offered high performance for the most demanding traffic workloads. Lastly, from all of the various vendors I've used, Cisco routsrs have the best TAC support.
