Q

EIGRP | Configures the default metric for the EIGRP process. The bandwidth is the minimum bandwidth of the route in kilobytes per second. It can be from 1 to 4,294,967,295. Delay is route delay in tens of microseconds. It can be 1 or any positive number that is a multiple of 39.1 nanoseconds. Reliability is the likelihood of successful packet transmission that is expressed as a number from 0 through 255. The value 255 means 100 percent reliability; the value 0 means no reliability. Loading is the effective bandwidth of the route that is expressed as a number from 1 to 255 (255 is 100 percent loading). MTU is the smallest allowed value for the MTU, which is expressed in bytes. It can be from 1 to 65,535.
