The document outlines Juniper's approach to enterprise networking, emphasizing a unified architecture through their ONE Junos platform, which ensures simplicity and investment protection. It details various network building blocks, including the QFX and EX series switches, as well as different fabric solutions such as Virtual Chassis and QFabric. Additionally, it highlights the two pillars of enterprise networks: campus and data center, showcasing their capabilities and benefits for scalability and reliability.

1. Juniper for Enterprise

Juniper System Engineer

2. Agenda
• Enterprise network – Juniper Approach
• Network building blocks
• Fabric solution
• Virtual chassis
• Virtual chassis fabric
• Fusion
• Enterprise networks – two pillars: campus and data center

3. Enterprise Network – Juniper Approach

4. Juniper Approach
• One Junos – common CLI, management and reporting
• General purpose vs specialized ones
• Keep it simple
• Use specialized ones when it makes sense
• Do not create boxes when there is no strong need to
• Think how you scale – investment protection

7. General purpose vs specialized ones
• Limited number of devices – we are not artificially increasing number
of units in our price list
• Data Center – 10GE/40GE/100GE switches are designed for DC
(QFX series)
• Data Center – 1GE use of general purpose model (EX4300)
• Campus access – use of 1GE general purpose model (EX4300)
• Campus core – designed for this task (EX4600)
• WAN connectivity – EX9200 or reuse of MX series

8. Investment protection
• Additional devices can form Virtual Chassis with already installed
ones (no links blocked by spanning tree)
• Each new VC member can increase number of available uplink ports
• Data ports can be used for VC connection – longer range and no
need to buy special stacking cable or ports
• Not only ring VC topology – full or partial meshed supported
(including nonblocking 5 times EX4300 VC)
• EX4300 1GE access switch can be reused in VCF topology as leaf
switch
• QFX 10GE DC switch can be reused in VCF as spine or leaf switch
