: Design the network architecture with scalability and future growth in mind.
The REN-2 link typically utilizes high-speed Ethernet or PCIe-based interconnects to ensure low latency and high bandwidth for control plane operations. While specific speeds depend on the generation of the hardware (e.g., PTX10000 or MX2000), these links are designed to prevent bottlenecks between the CPU and the switching fabric. Interface Integration
Don't failover yet. Simply restart the backup Routing Engine:
VXLAN encapsulates original Layer 2 Ethernet frames inside Layer 3 UDP packets, allowing them to traverse any standard IP routing core effortlessly. 2. VPLS Over GRE or IPsec (The Heritage Solution)
