Andy,
sh ip route on R3 and you will see the result. AD can be manipulated on local
router only so it's normal behaviour.
one question, why do you want to lower AD of summary routes?

Subject: Eigrp with manual summary trouble
Hi group,
I'm testing eigrp with manual summary feature.
My topo here: R3__s1------------------------s1__R5
First R3 advertises 192.168.0.0/24 ; 170.10.0.0/24 and 3.3.3.0/24 to R5.
Then i do summary them in the following manner:
R3#sh run int s1
interface Serial1
ip address 100.0.0.3 255.255.255.0
ip summary-address eigrp 100 192.168.0.0 255.255.0.0 5
ip summary-address eigrp 100 170.10.0.0 255.255.240.0 50
ip summary-address eigrp 100 3.3.0.0 255.255.0.0
I were thinking that, 192.168 and 3.3.0.0 will appear in R5's routing table
with AD=5, and 50 for 170.10
But let see what is in R5 routing table:
R5#sh ip ro
Gateway of last resort is not set
170.10.0.0/20 is subnetted, 1 subnets
D 170.10.0.0 [90/2523456] via 100.0.0.3, 00:25:07, Serial1
100.0.0.0/24 is subnetted, 1 subnets
C 100.0.0.0 is directly connected, Serial1
3.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
D 3.3.0.0/16 [90/2497856] via 100.0.0.3, 00:25:07, Serial1
5.0.0.0/32 is subnetted, 1 subnets
C 5.5.5.5 is directly connected, Loopback0
D 192.168.0.0/16 [90/2395456] via 100.0.0.3, 00:25:08, Serial1
These routes still keep their internal ad (90).
So what's the problem here ? or there something missing in my config ???
This is the config file:
=========================
R3#sh run
Building configuration...
hostname R3

interface Loopback0
ip address 3.3.3.3 255.255.255.255

interface Serial1
ip address 100.0.0.5 255.255.255.0
clockrate 64000
!
router eigrp 100
network 100.0.0.0

==================-=====
TIA.
