Mani,
        Are you sure that the 255 is the administrative distance?

Hi John,
 
The number 255 you are talking is admin distance and not metric, so
changing to 255 make no meaning. To deny eigrp routes to a neighbor use
(A.) -routere)#distribute-list 100 out e 0 and access-list 100 deny ip
any any
or
(B.)-router)#eigrp stub receive only
 
PS:To not to advertise a eigrp out of specific interface(say e0 and s1)
(A.)use passive interface e0 and s0
or
(B.)Advertise eigrp on other interfaces with a interface ip and wild
card mask of 0.0.0.0
eg;network 10.1.1.1 0.0.0.0<--Make to advertise eigrp out only this
interfaces

if i wanted to block all eigrp routes from exiting to the next hop would
it
be:

offset-list 1 out 255 s0/0

access-l 1 permit 0.0.0.0 255.255.255.255 ?

i wasn't sure since rip's metric would be '16' for offset but i'm not
sure
about eigrp.
thanks in advance
