  • Cisco ISR 4000 Series
4K Cisco Routers are used across the whole organization. We use them for WAN connectivity. A general design is with MPLS and DMVPN as backup. Compared to other vendors they are pretty solid, but there are the "usual" Cisco bugs, but I guess nobody is 100% exempted.

  • 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
Cisco is the leader of the market and usually, everyone knows Cisco and Cisco CLI, and maybe also [have] a certification. So in this sense, every company has some Cisco Routers for sure. Back to the topic, I would say use Cisco Router if there is expertise with Cisco, but in general, it's not a bad idea to look for something else.
  • We try to keep the uptime of the network to 99.9%
  • In general Cisco equipment is too expensive, but until the business is willing to pay, we will stick with it
A typical example is WLC with ISE. It works with other providers as well (i.e. Aruba), but there is more effort to get what you need. Regarding Routers and switches, it's not a big deal if the vendors are different, while it's really important that all the switches (at least in the same site) are from the same vendor.
Routers are not intended to secure your network...and actually the ZBF, that is the only thing is close to a firewall, is pretty bad. It works, but it's not even close to an ASA, and the ASA is not that good compared to Palo Alto or Checkpoint. And again there are continuously bugs that affect security.
Honestly I have experience with other vendors (Huawei and Brocade), but just for LAN and Data Center. I always used Cisco Routers.
We are evaluating a move to SD-wan and a potential vendor is Silverpeak. The idea behind this is completely different and also Cisco offers an SD-WAN solution. It means that you don't have to deal with CLI anymore and it's just GUI.
  • WAN devices for MPLS and DMVPN
  • Voice gateways
  • Internet edge
  • Product Usability
  • Prior Experience with the Product
  • Existing Relationship with the Vendor
Usability is the key factor. There are tons of guides on the Cisco websites and it's pretty easy to find a design solution or to solve an issue.
Furthermore the routers are pretty stable from hardware prospective. Routers are also less affected by bugs compare to switches, even if they run the same version (denali, Everest or Fuji)
I suggest always to create a template, better if automatic and preferably with a scripting language. It must be scalable and adaptable.
Then all the routers in the network will look exactly the same and it will help a lot the troubleshooting and it's going to be without errors. A team from another country continent won't be lost looking to a standard configuration.
In general Cisco had always the same policy for support, but I have the feeling that routers are less problematic when talking about bugs and in general the TAC engineers are more skilled compared to other areas. Not considering the huge problem of Cisco clock of 4331 in 2018 (we had to replace all of them due to an hw issue), the support for routers is rather good.
Cisco doesn't sell to customers directly, unless you are an ISP or a gold partner. So every time you must use a reseller. Once a clear process is in place, there are no problems. This is valid within the same country or continent. If you have to purchase in Asia you have to find a new reseller and start from scratch. I suggest to find a global reseller. It will also avoid problems with the discount.
Post sale is fine as long as you have smartnet in place. It's not cheap, but in case of problems you are covered (for hardware and software).
It's not necessary to buy smartnet every year for all the routers. You can keep spares in some sites. I suggest to buy smartnet for important sites or where it's hard to get a replacement.
Keep in mind that in most all the countries there is lifetime warranty for hardware.
This really depends on the strategy of the company. If you have a medium size team with expertise, there is no real sense to buy Cisco Services.
Of course with limited resources, I guess there is no real choice, but it's also matter of budget. Sometimes also resellers sell this kind of service and it could be cheaper.
I suggest to speak with your Cisco account manager and present your plan/design asking to involve someone from the technical side. They will help, and most probably for free.

  • Not Sure
  • Best for a business of any type.
  • Home office may be less appropriate due to price and higher skill set needed to operate.
  • Reliable
  • Good support (Cisco TAC)
  • Needs minimum maintenance
The company uses Cisco UC and all of our core networking equipment including access points is Cisco made.
We use Cisco ISR to send netflow to a collector.
In recent years we have only used Cisco routers.

Price vs reliability vs ease of use
All of my support requests always resulted in resolution even some more difficult cases took longer time (weeks).

Attention to detail, experience with the product, experience in networking.
  • None
  • No new ways are currently planned.
We renew Cisco end of life devices with current models.
Yes
I replaced several less known router products (i.e. kentrox, package) as well as routers from Juniper in the past in order to keep the network uniform, reliable, and have access to good technical support.
I evaluate Cisco products on regular bases as new models become available and old devices are being replaced.
  • Implemented in-house
Yes
Plan, purchase, configuration, deployment
Change management was minimal
  • Each implementation can have its set of quirks however in case of Cisco routers things are straightforward.
Its a good idea to have an active Smartnet contract before each larger deployment.
Yes
Cisco Smartnet is an important contract for certain Cisco devices as not only tech support but also new software releases are made available.
No
I dont find this question neither appealing nor relevant as exceptional customer service and similar are just buzz words.

  • Video
  • Routing
  • None known

  • Cisco ISR 4000 Series
43xx and 44xx this is our standard for WAN services. We have them deployed globally at our edge locations. We are using the ASR model in our DCs and core.
  • 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.
  • The licensing of these boxes can get expensive and confusing.
  • The uptime has been good. Building the network with the 4k platform is easy so there is less time spen training our deployment teams.
We have a mixed LAN of Cisco and non-Cisco there are no issues connecting. In the past, with older models of this product line, we did have issues connecting to some extreme switches but it seems that has been resolved on the 4K platform.
Our infosec team is constantly scaning and hardly ever finds an issue other than issues related to configuration. Running UCS on the 4K and running firepower seems like an idea that has some potential in our network. The 4K platform is flexible and can enhance your security posture.
We have been using Cisco Routers for a very long time and compared to other routers I see some improved metrics with regard to uptime. The 4K supports our robust QoS policy which gives us maximum application experience on our network.
They are the powerhouse when it comes to IP routing. The ease of use is great. The licensing requires an MBA.

Cisco Routers are in use to provide support for multi-protocol routing and basic ACL functionality. They provide our BUs with reliable connectivity options to the internet and branch locations.
  • Route packets and connect to circuit vendors
  • TAC support for routers is great
  • Hardware longevity is awesome as well
  • They need to finish the SD-WAN integration with Viptela
Cisco Routers are great in data centers. Other vendors come into play in the smaller router sizes.
  • Cisco hardware and support is at the upper end of the prices for route/switch which sometimes makes it hard to get the same ROI
  • Cisco is usually supported by third-party tools
Comparability is always a concern and Cisco is generally compatible with most other vendors products.
