RE: Modifying AD for EIGRP external routes

I came into the need 2 days ago and I found that it was better to raise the
admin distance of the other igp (ospf in my case) to 171. This way the
external distance for EIGRP will be preferred,

Subject: Modifying AD for EIGRP external routes

Has anybody tested reducing the AD of external EIGRP routes from 170 to some
other value (say 91).
 
I have tried the distance command under EIGRP but it changes the distance
only for internal eigrp routes and not external eigrp routes.
 
Here is the relevant configs...
 

router eigrp 318
 redistribute eigrp 300 route-map 300to318
 offset-list 99 in 20 Serial0
 network 172.16.123.0 0.0.0.31
 neighbor 172.16.123.1 Serial0
 neighbor 172.16.123.4 Serial0
 distance 91 172.16.123.1 0.0.0.0 98
 distance 91 172.16.123.4 0.0.0.0 97
 no auto-summary
!
 
access-list 97 permit 10.2.4.0 0.0.3.255
access-list 98 permit 172.16.15.0 0.0.0.15
 
 
SH IP ROUTE
 
D EX 172.16.15.0/28 [170/46738176] via 172.16.123.1, 00:00:07, Serial0
D 10.2.4.0/22 [91/46251776] via 172.16.123.4, 00:25:30, Serial0
 
 
FYI-- 172.16.123.1 is sending external EIGRP routes and 172.16.123.4 is
sending internal EIGRP routes and I am trying to make both these routee to
show up with AD 91 in the routing table.
 
 
thanks,
 
MD
