protocol for policy enablement across physical and virtual switches. Southbound interfaces are implemented with some called Service Abstraction Layer (SAL), which talks to the network elements via SNMP and CLI. Note: Cisco OpFlex is a southbound protocol in a software-defined network (SDN). 18.Which two statements about EIGRP load balancing are true? (Choose two) A. Cisco Express Forwarding is required to load-balance across interfaces B. A path can be used for load balancing only if it is a feasible successor C. EIGRP supports unequal-cost paths by default D. Any path in the EIGRP topology table can be used for unequal-cost load balancing E. EIGRP supports 6 unequal-cost paths Answer: B E Explanation: EIGRP provides a mechanism to load balance over unequal cost paths (or called unequal cost load balancing) through the “variance” command. In other words, EIGRP will install all paths with metric < variance * best metric into the local routing table, provided that it meets the feasibility condition to prevent routing loop. The path that meets this requirement is called a feasible successor. If a path is not a feasible successor, it is not used in load balancing. Note: The feasibility condition states that, the Advertised Distance (AD) of a route must be lower than the feasible distance of the current successor route.
