How has the EIGRP routing protocol improved by having interface delay measured in picoseconds instead of microseconds?

  • It speeds up convergence.
  • It allows for a larger number of networks.
  • It provides better metrics for high speed interfaces.
  • It improves performance and communication time between directly connected neighbor routers.
Answers Explanation & Hints:

The original values used to calculate EIGRP metrics were in microseconds for delay and kilobytes per second for bandwidth. When using EIGRP wide metrics, the delay units are picoseconds and within the formula, the metric is found by multiplying by 65,535 instead of 256, thus providing support of interface bandwidth up to 655 terabits per second.
