When we are doing redistribution, EIGRP asks for specific parameters and the
Big Dogs Really Like Me acronym stands true.
R1(config-router)#redistribute ospf 1 metric ?
<1-4294967295> Bandwidth metric in Kbits per second
R1(config-router)#redistribute ospf 1 metric 10000 ?
<0-4294967295> EIGRP delay metric, in 10 microsecond units
R1(config-router)#redistribute ospf 1 metric 10000 100 ?
<0-255> EIGRP reliability metric where 255 is 100% reliable
R1(config-router)#redistribute ospf 1 metric 10000 10 100 ?
<1-255> EIGRP Effective bandwidth metric (Loading) where 255 is 100%
loaded
R1(config-router)#redistribute ospf 1 metric 10000 10 100 100 ?
<1-65535> EIGRP MTU of the path
R1(config-router)#redistribute ospf 1 metric 10000 10 100 100 1500
But when doing a change in metric weights, it simply asks for K1 - K5
values, and their order should be according to EIGRP's formula, hence "The
Big Ladies Dont Run Much" acronym stands true.
as in the formula : metric = [K1*bandwidth + (K2*bandwidth)/(256 - load) +
K3*delay] * [K5/(reliability + K4)]
thats what i believe.
