Aminul,

The best way to verify this is by labbing it up. Here's my lab with
different eigrp ASes on R2:

Note that I did not specify metric, or default-metric for redistribution
between eigrp10 and eigrp100 on R2. As Herbert stated, EIGRP will carry
over the metrics from one AS to the other.

        Yes, you need to define the metric even for the different
processes of
        eigrp, otherwise you won't get it.
