Re: Metric to redistribute in EIGRP ....

Hi All,

Just to add on, redistributing static routes into EIGRP also does not
require setting the seed metric. If I remember it correctly, the bandwidth &
delay values of the egress interface of the static route is considered in
the metric calculation, just like connected routes being redistributed into
EIGRP.

I typically set the values for Reliability, Load, and MTU in the seed
metric to 1 1 1 respectively because they are not used in the metric
calculation by default anyway. Anyone can comment on this?

Thank you.

B.Rgds,
Lim TS
