Inter-VLAN routing is a process of forwarding network traffic from one VLAN to another using a router.
To allow devices connected to the various VLANs to communicate with each other, you need to connect an intermediary network device. For the record, each VLAN is a unique broadcast domain, so, computers on separate VLANs are, by default, not able to communicate. There is a way to permit these computers to communicate; it is called inter-VLAN routing.

One of the ways to carry out inter-VLAN routing is by connecting a router to the switch infrastructure. VLANs are connected with unique IP subnets on the network. This subnet configuration enables the routing process in a multi-VLAN network. When using a router to facilitate inter-VLAN routing, the router interfaces can be connected to separate VLANs. Devices on those VLANs communicates with each other via the router.

There are different methods for accomplishing inter-VLAN routing:

i. Traditional Inter-VLANrouting. This type of packet routing process requires multiple physical interfaces on both the router and the switch.

ii. Router-on-a-stick. This is a type of Inter-VLAN router configuration in which a single physical interface routes traffic between multiple VLANs on a network.

A router interface is configured to operate as a trunk link and is connected to a switch port configured in trunk mode. The router performs this type of routing process by accepting VLAN tagged traffic on the trunk interface coming from the adjacent switch and internal routing between the VLANs using sub interfaces. The router then forwards the routed traffic-VLAN tagged for the destination VLAN out the same physical interface.

Cisco Corporation provides a wide array of certifications for technically minded people who want to specialise in supporting their hardware and networking equipment. There are three levels of certification in the General certifications path, from Associate to Professional to Expert, with certification paths covering Routing and Switching, Network Design and Architecture, Network Security, Service Provider, Storage Networking and Voice Certification.

 While not directly comparable to college degree programs in all aspects, you can think of the Associate certification as being roughly equal to an Associate of Arts degree in the generalised technology area, the Professional as being just shy of a Science degree, and the Expert certification as being broadly comparable to a partial Master’s Degree program.

 Many professionals end up getting an Expert certification in one area, and branching out with Associates and Professionals in a few supporting topic areas.

 Going beyond the generalised certification programs, Cisco also has Specialist Certifications, all of which require an Associate or better certification to take the exam. These get significantly more diverse, with subjects covering Advanced Routing and Switching, with field specialists (people who trouble shoot problems), sales specialists (people who are good at defining what range of Cisco products a customer needs and getting them in place) and solutions specialists (who design full architected systems for customers).

 The most common Specialist certifications deal with data centres, and there are eight of them, usually split between Support, Design and Sales, for Application Services, Network Switching interfaces, and Network Storage Certifications. These build on several foundation skills.

 The second most common Specialist certifications cover IP (Internet Protocol) Communications Certifications; these are, in effect, engineering certifications, and cover the range from Telephony Network Design services, Contact Centre certifications, generalised IP communications certifications and more. What these certifications do is give a baseline for setting up networking solutions for large organisations.

 One of the most demanded sets of specialisation certifications include the VPN and Security specialisations, which cover everything from firewalls to generalised security technical’s to architectural setup certifications. There are also specialisations covering wireless LAN and channel partner certifications.

 All of these certifications (both General and Specialist) have attended course requirements and exams; you can expect that a typical course will run from three weeks (at the Associates level) to six to eight weeks, and be followed by an exam; expect to pay a largish fee for these certification processes.

 The up side of these certifications is that they give you a leg up in the job market when working with this particular hardware set and these protocols. Therefore Cisco certifications are an excellent investment in your IT future.

Cisco Certified Network Professional (CCNP) certification is a much valued credential for any IT professional. It is basically a professional level Cisco networking certification that ascertains an individual’s good knowledge and skills in the networking and troubleshooting fields. They are capable enough to install and configure LANs (Local Area Networks) and WANs (Wide Area Networks) for small as well as large organizations that comprise of networks from 100 – 500 nodes. Also, the CCNP certification covers such vital networking concepts and several specialized subjects like virtual private networks (VPN), broadband technologies, quality of service (QoS), converged networks and security. CCNP certification has a prerequisite in the form of CCNA (Cisco Certified Network Associate) certification.

Only recently, there was a slight alteration in the CCNP certification system with the Composite exam being introduced. CCNP certification exam generally has a four exam and a three exam path. A CCNP certification is valid only up to three years. A candidate, who is interested in keeping his CCNP certification active, will have to recertify himself by taking certain professional level Cisco exams.

A CCNP certification is apt for those who boast of at least a years networking experience and want to notch up their skills and expand their work horizon by working on advanced network solutions independently. Those who acquire CCNP certification will have shown their skills that are are crucial to roles in enterprises like that of a support engineer, network technician, network engineer or systems engineer.

A CCNP certification is highly valued and recognized by most reputed IT employers. It gives an IT professional an additional edge over the other non CCNP certified individuals.

It isn’t easy to clear a CCNP certification; it requires a lot of hard work and thorough understanding of every concept. Mere mugging up of concepts won’t get you through all the exams. The fact that this exam is so tough to crack, adds to its value and credibility. An IT employer can take it for granted that a CCNP professional is an expert at networking and troubleshooting skills and has immense knowledge about related specialized fields
