- Manage multiple connections
- Great management tools
- Awesome security
- Complex licensing. One could invest as much time learning their licensing schemes as you would studying for a CCIE.
- Most GUI software is written in Java and can do a lot of dumb things--specifically the ADSM software used to configure ASA's.
- We use them for PSTN access and they are able to handle multiple concurrent calls without any issues.
- We also use DSP cards on them for conferencing and transcoding resources and they are very efficient in terms of processing.
- They provide high uptime, it's like you plug them and they run forever until you bring them down.
- Certain models of the new ISR 4400 series routers have only single source power supply. We would like to have dual source power supply for high availability.
- We don't have any other issues.
- They function reliably
- They are easy to install
- Cost of replacing them as we have to rely on another entity for the requisition of the equipment, and they are always looking to cut cost, so they don't always go with our recommendations
- Once they are configured you can basically forget them until your (NMS) network management systems notify you of an issue
- Simple EIGRP configuration
- Super cost effective
- Most are single power supply
- If they aren't a full 19" 1U device you have to purchase rack ears separately from the device
- VPN tunneling can be a bit of a configuration challenge
- They are very reliable and just keep working.
- I have not had a hardware issue to date with any router.
- Provide additional services than just routing.
- Don't limit data throughput based on licensing.
- Provide an easy way to expand cards in the router without having to restart it.
- Somewhat easy to design and configure
- When we have problems TAC is always able to help us with the issues
- The ability for carrier diversity and backup links controlled by route maps makes for a great platform
- Not having a built in rollback feature for when a configure change causes unexpected results
- Different command suites on the ISRs verses nexus
- iOS upgrades that cause existing features to sometimes respond unexpectedly
- DMVPN is a fantastic, de facto industry standard for remote office connectivity.
- Cisco routers can be integrated with Cloud Web Security, Encrypted Traffic Analytics, SGTAG policy enforcement, and so much more.
- Voice integration, particularly Survivable Remote Site Telephony (SRST) is outstanding.
- Real-world performance statistics
- Provide a platform for flexible path manipulation.
- Advanced scripting and response features.
- Modular capacity to run additional services like compute, VoIP, etc...
- Further support of open functions and API integrations.
- Improved application intelligent routing and optimization.
- Better extraction of telemetry and event data to open repositories.
Not well suited for RAVPN and firewalling.
- Supportable, I know we can find the information needed to support
- Reliability, it works.
- Lacking solutions for the small office.
- Programmability, I want to use python for everything
- Cost for licensing and support
- App identification with NBAR2 is great. We use it in conjunction with our robust QoS.
- Routing is obviously what built Cisco and it is as expected rock solid on the isr4K platform.
- We are looking foward to the intergration of Viptela software on to this platform. Having this on the road map will help our migration.
- We have found several code bugs and it has caused outages on our network.
- The license program is a bit confusing - there are several tiers and we have had issues with Cisco ONE portability.
- All WAN routing scenarios and IP conversation scenarios.
- The 4K platform could be used in a small DC.
- Easy to use, simple to operate, highly predictable. IOS/IOS-XE is well known and there is a virtually limitless pool of engineers who know this platform and if not having direct experience, can apply knowledge from other IOS/IOS-XE with very little adjustment.
- Extremely flexible due to wide variety of interfaces. NIM and SM-X provide a great deal options: TDM, E&M, FXO, FXS, switches and servers are all options.
- Robust IP feature set: Routing protocols, NBAR, Netflow, QoS, DMVPN. This large IP feature set gives us the ISR makes it a highly re-usable router, capable in many different use cases.
- I would like to see an extremely simpler licensing. ISR still suffers from Cisco licensing complexity.
- I would like to see improvements in IOS-XE incorporating some of the capabilities found in IOS-XR e.g., config commits and rollback. This may require an IOS fork but unifying IOS-XR and IOS-XE would be a welcome change.
- I would like to see unified SD-WAN, Voice, and IOS-XE image. I believe this is already on the roadmap.
- Basic/Standard Routing functions
- Handle all standard routing protocols
- Price. Even the smaller units aren't cheap.
- Software stability. Once you get a stable version stick with it. Bugs can be more common than they should be.
- Encryption with DMVPN is rather easy and customization is pretty good
- QOS, even if the "sauce" that Cisco uses is somehow not known
- The hardware in general is solid and with two power supplies (4431 and 4451) the resilience is quite good
- ZBF - The zone base firewall is complicated and not that efficient, better than an ACL, but not a real Firewall.
- Bugs - it's not possible to upgrade an IOS every several months due to bugs
- They are too expensive. Even if they are the leader of the market, they are not necessarily the best
- For those who are used to Cisco, they are easy to use.
- They interoperate well with other vendors. Everyone is compatible with Cisco.
- Performance is excellent. I’ve never had a Cisco router that was unable to perform as Cisco says it will.
- The CLI can sometimes be inconsistent. You get used to it, but could be better.
- Programmability is hit and miss. Overall, newer code has better support for programmability.
- Cisco’s pricing is relatively high. No one pays list price, so list prices are very high and can be off putting at first.
Cisco Routers Scorecard Summary
About Cisco Routers
Cisco routers support secure, reliable enterprise connections. These enterprise routers help users implement an intent-based, future-ready WAN that is constantly learning, adapting, and protecting. Deploy routers for the branch, cloud, co-location, or the data center with any type of connectivity, including MPLS, Internet, and 4G LTE.
With over 30 years of experience and an end-to-end portfolio, Cisco routing solutions can deliver for today’s networking needs what our competitors can’t. We help customers successfully manage technology transitions. Embedded security detects threats in mere hours instead of months. And we’ve studied how networks are consumed, applying those learnings to the new network.
Cisco routers deliver the first open, intent-based networking platform across the branch, WAN, and cloud. We provide end-to-end security, automation, and analytics with award-winning services and support.
