Hey Sidda,
For the ACL try this:
Access-list 24 permit ip 24.24.4.0 0.0.8.0 (matches 24.24.4.0 and
24.24.12.0)
Access-list 24 permit ip 24.24.7.0 0.0.8.0 (matches 24.24.7.0 and
24.24.15.0)
That's the shortest ACL to match just those 4 network addresses without over
matching.
With respect to metrics you can pick anything you like, but I recommend
picking something that is representative of your underlying network. Going
into EIGRP I normally use the interface properties of the source interface
for the routes. For RIP I use a low number that still shows a few hops (like
3) and for OSPF I leave the default (although I prefer Type E1).
Cheers,

Subject: TWO more questions.
A)
I have series of networks from 24.24.1.0 /24 to 24.24.16.0 /24. But
want to pick only few networks from this series using ACL. For
example- 24.24.4.0 to 24.24.7.0 AND 24.24.12.0 to 24.24.15.0
What is the Exact ACL for this?
acess-list 24 permit 24.24.0.0 0.0.15.0 ( this picks all networks from
24.24.1.0 to 24.24.15.0 ). I don't want all networks, can this be done
with JUST a ACL alone?
B) If nothing mentioned about metrics, while redistributing from one
routing protocols to other like from rip/ospf to eigrp and vice versa.
Does it it mean can I use any mertric number or some exact numbers to
be used?
Regads,
Sidda.
