Hello Khan,

actually you need to provide a seed metric when redistributing a dynamic protocol into EIGRP.

So the actual values are important only if you have multiple redistribution points and you want to have a preferred exit point from EIGRP domain

however the parameters are:

100000 1000 255 1 1500

first Bandwidth in kbps = 100 Mbps

second delay in tens of microsec 10000 microsec = 10 ms

third reliability (255/255 good)

fourth is load (1/255 empty link)

fifth is MTU (1500)

the idea is to take the parameters of the router interface in OSPF 12 domain that can be a FE 100Mbps in this case

With default K values only BW and delay are used to calculate the seed metric and MTU is inserted in its own field in the data structure that represents the external route.

Hope to help

Giuseppe
