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
