A network administrator needs to learn information about EIGRP load balancing to configure an EIGRP network. Which piece of information is accurate about this subject?

• The variance multiplier is obtained by dividing the successor route metric by the feasible successor metric.
• Any feasible distance of a feasible successor with a metric above the EIGRP variance value is installed into the RIB.
• The maximum equal-cost multipathing routing for EIGRP is four routes.
• The EIGRP variance value is the feasible distance for a route multiplied by the EIGRP variance multiplier.

Explanation: EIGRP allows multiple successor routes (with the same metric) to be installed into the EIGRP RIB. This is called equal-cost multipathing (ECMP) routing. The actual default maximum ECMP is four routes, but this value can be changed with the maximum-paths maximum-paths command. EIGRP also supports unequal-cost load balancing changing the EIGRP variance multiplier. The EIGRP variance value is the feasible distance (FD) for a route multiplied by the EIGRP variance multiplier. Any FD of a feasible successor with a metric below the EIGRP variance value is installed into the RIB. Dividing the feasible successor metric by the successor route metric provides the variance multiplier.
