Distance: internal 90 external 170- The variance is set to the default value of 1, which requires all paths to have the same cost to be eligible for load balancing.
- The router is configured per-destination and per-packet load balancing.
- The router is configured to load balance over unequal-cost paths.
- The router is configured with automatic summarization.
Explanation: The output of the show ip protocols command shows "Maximum metric variance 1." In EIGRP, the default variance is 1, which means the router will only perform load balancing across paths that have the exact same metric (equal-cost). To enable unequal-cost load balancing, the variance must be configured to a value greater than 1 (up to 128). Additionally, the output explicitly states "Automatic Summarization: disabled," making that option incorrect [Source Output]. EIGRP's load balancing is also typically performed on a per-conversation (destination) basis rather than per-packet.
