Let me summarize some of the key takeaways related to CCIE R&S V5.1 Written Exam: Implement and Troubleshoot Static Routing as relevant to CCIE Routing and Switching (R&S) V5.1 written exam blueprint topics.

Exam Essentials

• A traffic storm occurs when packets flood the LAN, creating excessive traffic and degrading network performance. The traffic storm control feature prevents LAN ports from being disrupted by a broadcast, multicast, or unicast traffic storm on physical interfaces
• A private VLAN partitions the Layer 2 broadcast domain of a VLAN into sub-domains, allowing you to isolate the ports on the switch from each other. A sub-domain consists of a primary VLAN and one or more secondary VLANs
• IPv6 source guard is an interface feature between the populated binding table and data traffic filtering. This feature enables the device to deny traffic when it is originated from an address that is not stored in the binding table
