You are right John.

B L D R R for metric-weights. If you look at the equation for EIGRP
composite metric you should see that K4 provides the multiplier for
reliability, but without K5 being enabled, the denominator for the
reliability ratio is 0. Thus, the reliability component for the
composit metric would be 0.

Redistribution (B D R L M) just sets the values to be used for the
composite metric calculation as follows.

Composit metric = [K1*bandwidth + (K2*bandwidth)/(256 - load) +
K3*delay] *
[K5/(reliability + K4)]

ok, i think this actually may be incorrect, or partially incorrect when
you are setting a default metric or reistributing it is B D R L M
but if you are changing the metric-weights it is B L D R R from
what i
understand k4 and k5 have to do with Reliability.

someone please correct me if i'm wrong.

SAPRISSA(config-router)# default-metric 10000 100 255 1 1500

10000 = Bandwidth = K1 (Big)
100 = Delay = K2 (Dogs)
255 = Reliability = K3 (Really)
1 = Loading = K4 (Like)
1500 = MTU = K5 (Me)

Hi group

What does K4 and K5 stand for (which one is 'Reliability' and which one
is
'MTU')

AFAIK,

K1 - BW

K2 - LOAD

K3 - DELAY

K4 - ??

K5 - ??

Also, is there a way to find this out from the router quickly by using
the context sensitive help from any of the global/interface
configuration commands?

Thanks,

Raj
