How does SDN address the issue of scalability in large network infrastructures?
- By decoupling the control plane from the data plane, SDN allows centralized control, making it easier to scale and manage large networks.
- By using traditional routing protocols that automatically scale to accommodate network growth.
- By relying on complex distributed algorithms that dynamically adjust network resources.
- By limiting the size of the network to maintain manageable scalability.
SDN addresses scalability by decoupling the control and data planes, enabling centralized control for easier scaling in large networks.
How does BGP's route aggregation feature benefit network performance and scalability?
- Reducing the number of routing entries
- Increasing the BGP peer connections
- Utilizing MPLS technology
- Implementing OSPF as the IGP
BGP's route aggregation feature benefits network performance and scalability by reducing the number of routing entries in the routing table.
What is the primary advantage of using EIGRP over RIP in a network?
- Low bandwidth usage
- Rapid convergence
- Simple configuration
- Support for VLSM
EIGRP (Enhanced Interior Gateway Routing Protocol) has the advantage of supporting Variable Length Subnet Masking (VLSM) in comparison to RIP.
