Hi ,
I am having problem to understand the metric and the costs assigned during redistribution from eigrp and ospf .
For example :
Eigrp , bandwidth and delay , how do I assign this value . I am using a serial line with 2 Mb bandwidth . When I check the configurations , it has been distributed with the value of 10000 and something else . How I determine this value , should i use the default values .
Ospf , the cost , how do i define the cost , whether it's 30 or 50 , or should I use the default .
Thanks anyway .

Hello Alman,
when you set a default metric in EIGRP you specify values for the seed metric using
router eigrp 10
default-metric BW delay reliability load mtu
with default K parameters the seed metric is then calculated as
256 * (delay in tens of microseconds) + 256 * (10^7 / bandw [in kbps])
EIGRP requires to set a seed metric unless redistributing connected or static.
OSPF has default metric values.
For OSPF the most important decision is the metric type:
O E1 if there are multiple exit points (redistribution points) is to be preferred over default O E2 type.
Hope to help

Thanks Giuseppe,
If my serial link is 2MB ,I am sorry , I am still new in these ,
256 * ( delay in ten of microseconds ) this value, I believe , I will need to take it from the show interface command + 256 * ( 10>7 / 2000 kbps )
This value will give me , let says 1000
1000 the rest , i will put it as default .1000 100 30 50 255.
Is this what are you , trying to say
