When redistributing connected interfaces into EIGRP, you don't need to
specify the metric.

Antonio,

I believe with EIGRP redistribution we can not do away with NOT setting the
metric ? I believe redistribution fails complete;ly if no metrics are not
set for EIGRP ( as well as RIP ) unlike OSPF,IS-IS and BGP that have default
seed metrics ?

One common practice is to do a " show interface " on outgoing interface, and
use the values you get on that interface for BW,DLY,MTU etc.

Herbert.

In the particular case you are redistruting connected interfaces to eigrp,
and imo, the best is not to choose any metrics. This way eigrp will use the
interface original settings (bw, dly,...) to calculate the metric.

Regarding your question, you can use either option depending if you
have/have not some conditions and/or restrictions. But be carefull when you
are using method #2. Since the resulting metric is very high (2560025856),
it's easy to create a routing loop if additional redistributions are made
inside your IGP domain.

Hi,
     I have some doubt abt. the metric used when we redistribute protocols
into EIGRP. I come across materials that says

ie)
1) router eigrp 100
   redistribute connected metric *10000 100 255 1 1500 *route-map
CONNECTED-EIGRP

and also

2) router eigrp 100 redistribute connected metric *1 1 1 1 1 *route-map

CONNECTED-EIGRP

  Does this mean if the questions do not specify the* preferred metrics* we
can just do like in *2) *above and use any arbitrary values ?

Pls advice,
