CCIE R&S V5.1 Written Exam: Implement and Troubleshoot Multiproctocol BGP
I will be discussing Implement and Troubleshoot Multiproctocol BGP as part of Layer 3 Technologies and Fundamental Routing Concepts CCIE Routing and Switching (R&S) V5.1 exam blueprint topics.
Implement and Troubleshoot Multiproctocol BGP :
3.7.f Implement and troubleshoot multiproctocol BGP
3.7.f [i] IPv4, IPv6, VPN address-family
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.
- RD and v4 address are essential components of an MP-BGP VPNv4 address
- When BGP tries to install the best path prefix into Routing Information Base (RIB) (for example, the IP Routing table), RIB might reject the BGP route due to any of these reasons:
- Route with better administrative distance already present in IGP. For example, if a static route already exists in IP Routing table.
- Memory failure.
- The number of routes in VPN routing/forwarding (VRF) exceeds the route-limit configured under the VRF instance
