Study Notes
RIB vs FIB
- RIB (Routing Information Base) is used to create and manage a routing table.
- FIB (Forwarding Information Base) is populated based on the contents of the RIB.
- The FIB is utilized for making forwarding decisions based on IP routing contexts.
QoS Components
- Marking alters packets to change their treatment within the network.
- Traffic shaping alleviates congestion by buffering packets above the committed rate.
Cisco Express Forwarding
- Cisco Express Forwarding maintains two tables: the FIB and adjacency table.
- Forwarding decisions in CEF are made without direct involvement of the router's CPU.
On-Premises vs Cloud Infrastructure
- On-premises infrastructure offers lower latency for systems that are physically close, enhancing performance.
- Cloud infrastructure provides benefits like rapid scaling and resource allocation.
Traffic Policing
- Policing should be implemented as close to the source as possible to effectively manage traffic.
- Traffic that exceeds the defined rate is dropped in a policing mechanism.
Cisco SD-WAN Components
- vBond handles the orchestration plane in Cisco SD-WAN deployments.
- vSmart controller manages the control plane for the SD-WAN environment, ensuring effective network management.
Device Roles in Cisco SD-Access Fabric
- Edge nodes and border nodes play crucial roles in facilitating connectivity and security.
- Access switches are involved in connecting end devices to the network.
Client Access Control
- In Cisco SD-Access fabric, the Identity Services Engine (ISE) determines client access to the network upon connecting to an edge switch.
Cloud Deployment Benefits
- Efficient scalability is a significant advantage of cloud infrastructure, making it easier to adapt to changing demands compared to on-premises solutions.
