While core routing protocols lay the foundation, mastery of high availability, security, IPv6, and Quality of Service (QoS) distinguishes expert network designers.

High Availability: Designing Networks That Never Fail

High availability is a fundamental design goal that ensures networks remain operational despite faults, failures, or maintenance. For the CCDE practical exam, understanding how to architect resilient networks with minimal downtime is vital.

Key Principles of High Availability

• Redundancy: Duplication of critical components—links, devices, power supplies—to eliminate single points of failure. Designing for redundancy requires careful consideration of cost versus benefits, as introducing multiple layers of backup can increase complexity and expenses. However, the tradeoff often justifies itself through the increased uptime and reliability.
• Fast Convergence: Routing protocols must rapidly detect failures and reroute traffic to maintain service continuity. Fast convergence minimizes the window where packets could be lost or delayed, which is critical for real-time applications like voice and video.
• Fault Isolation: Designing networks that contain faults locally to prevent a failure from cascading across the entire infrastructure improves stability and ease of troubleshooting.
• Load Balancing: Distributing traffic across multiple paths optimizes resource use, prevents bottlenecks, and provides inherent redundancy.

Protocol Features Supporting Availability

• OSPF Fast Reroute: Loop-Free Alternates (LFA) provide precomputed backup paths that ensure rapid failover without waiting for global network reconvergence.
• BGP Graceful Restart and Route Refresh: These mechanisms help maintain routing stability during planned maintenance or unexpected disruptions by preserving forwarding state or refreshing route information without disrupting traffic flow.
• EIGRP SIA (Stuck-In-Active) Timers: Properly tuning these timers helps prevent long delays during network changes, improving protocol responsiveness.
• NSF/NSR (Non-Stop Forwarding/Non-Stop Routing): These features allow routers to maintain packet forwarding even while the control plane reboots or is updated, reducing traffic interruptions.
• MPLS Fast Reroute: Provides sub-50ms protection switching by redirecting traffic onto backup Label Switched Paths (LSPs), which is vital for carrier-grade networks requiring near-zero downtime.

Architectural Strategies

• Hierarchical Network Design: Separating core, distribution, and access layers enables localization of failures and efficient traffic aggregation.
• Redundant Data Centers: Geographically dispersed sites with synchronized configurations allow failover and disaster recovery.
• Access Layer Designs: Moving from Layer 2 to Layer 3 access reduces broadcast domains and improves scalability and fault isolation.

Exam Focus

Candidates must be able to design architectures that incorporate these availability features and clearly articulate the trade-offs involved. The ability to weigh complexity, cost, and performance to propose practical solutions is critical.

Security: Integrating Protection into Network Designs

Though not the primary focus of the CCDE exam, security remains an essential element of network design, particularly in today’s environment of increasing cyber threats.

Routing and Infrastructure Security

• Authentication: Implementing authentication mechanisms like MD5 or SHA for routing protocols (OSPF, EIGRP, BGP) prevents unauthorized route injections and protects routing tables.
• Prefix Filtering: Restricting accepted routes protects against route leaks or hijacks that can cause traffic misdirection or blackholing.
• Control Plane Policing (CoPP): Protects router CPU from denial-of-service (DoS) attacks by limiting traffic rates directed to control plane processes.
• Infrastructure Segmentation: Separating management, control, and data traffic reduces exposure of critical network components.

Service Provider Security Measures

• Remotely Triggered Black Hole Filtering: Quickly isolates and discards traffic from sources of DDoS attacks.
• DNS Security Extensions (DNSSEC): Ensures integrity and authenticity of DNS responses, preventing cache poisoning attacks.
• Secure BGP Practices: Utilizing Route Origin Authorization (ROA), Resource Public Key Infrastructure (RPKI), and strict prefix filtering enhances the security of interdomain routing.
• Mitigation of Common Attacks: Designs must anticipate threats like SYN flooding, IP spoofing, and reflection/amplification attacks and incorporate mitigation techniques.

Design Considerations

Balancing security with network performance is crucial to avoid introducing bottlenecks. Ensuring redundancy of security appliances and rapid incident response plans strengthens overall resilience.

IPv6: Preparing for the Future of Networking

IPv6 adoption continues to accelerate, and the CCDE exam expects candidates to understand its fundamentals and integration challenges.
