Cisco vs Juniper:  Which one is better ??!!

Game of Pons and Cons We can’t say which one is better than the other.In fact to be considered the choice for your network, Cisco devices meet the needs of organizations and offices of all sizes and sorts. As for Juniper, it has some product lines that are similar to Cisco devices, but have their own network hardware lines and IT solutions for different network demands. Besides Cisco and juniper, there are other brand that are also effective and reliable. I asked some Juniper as well as Cisco guys and they gave me many different answers and some of them refused to answer and blocked me 😄:

Cisco pros: 👍

1) HUGE portfolio regarding Routers, switches, firewalls, wireless, video conferencing, phones, cable modems, security cameras, storage networking, and even servers and racks; they literally are a player in every area of your infrastructure!

2) support model is well understood. Never have to worry about whether they can get the parts there or not.

3) IOS is well understood.

4) Has more enterprise/legacy features.

5) diverse , strong and solid Security Solutions

6) Scalability (Fact: Cisco set the Guinness World Record in 2004 for the world’s highest capacity router — a record that still stands today.)

7) Great customers’ success: From the certification paths to Cisco Live to the support forums, Cisco provides a wide variety of programs and resources to ensure their customers’ success.

Cisco cons: 👎

1) Different IOS depending on the Product is some cases.

2) No support for modular upgrades. It's all or nothing.

3) You can't encrypt multicast traffic without using GRE tunnels. That means:if you want to encrypt OSPF & data packets, you *have* to use GRE.

4) Multiple IOS images can be a pain to manage.

5) Control plane is *just* being protected with later IOSes.

Juniper pros: 👍

1) Operational features such as "commit" and "rollback n" can really make backing out of changes a no brainer.

2) Performance is not really in question. Info: This is achieved by custom ASICs (Application-Specific Integrated Circuits) which are essentially electronic chips designed to do some of the heavy lifting that would otherwise be done in software.

3) IPSec can be encrypted since the AS/ES PICs are IP addressable.

4) High availability is pretty much built in.

5) Some accounting counters are done on the line cards. Easy to get stats.

6) Control plane is well protected.

7) You can do modular upgrades to JunOS.

8) more cost effective.

Hint: The final compelling argument for a Juniper switch is the JUNOS operating system. It offers two major benefits over Cisco's offerings:

Modular design: Every process and component in a Juniper network setup is isolated from every other (Thank to the FreeBSD). One module crashing will have no effect on the rest of the system.

Single train compatibility: Every Juniper switch, router, or other product runs the same JUNOS system. It's built for simple inter-operability across the system Juniper cons: 👎

1) Support model is still not proven. Can they hit every office that I have??? Not sure.

2) The J series routers are a new item. Granted, Juniper's mantra of same JunOS everywhere! is a plus.

3) The J series has a button that will reset the router to a "known good" configuration. Can be quite useful for remote locations.

4) No support for legacy protocols. May be a deal breaker for some enterprises.
