I'm redistributing RIP and connected subnets into OSPF domain. I forced the redistributed routes to be metric-type 1.
According to my configs, redistributed RIP routes will get a 30 metric value, and connected redistributed routes will get a 20 metric value.
However, I have other metric values on the output of "show ip route".
Redistribution occurs on router C (R0).
what you see is correct.
O E1: the seed metric is counted together with metric to get to the ASBR
so you have a 64 offset that is the ip ospf cost of R5 serial interface to reach R0 /RC
do a sh ip ospf int serx/y to verify this
so you get 84 or 94 metric
Hope to help
