Hi Lim,
It works just fine, please clear ip route *:
Rack1R1(config)#router eigrp 10
Rack1R1(config-router)#no aut
Rack1R1(config-router)#no auto-summary
Rack1R1(config-router)#network 155.1.146.1 0.0.0.0
Rack1R1(config-router)#
1d21h: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 10: Neighbor 155.1.146.4
(FastEthernet0/0) is up: new adjacency
Rack1R1(config-router)#
Rack1R1(config-router)#network 150.1.1.1 0.0.0.0
Rack1R1(config-router)#int f0/0
Rack1R1(config-if)#ip summary
Rack1R1(config-if)#ip summary-address eigrp 10 155.1.0.0 255.255.0.0
Rack1R1(config-if)#
1d21h: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 10: Neighbor 155.1.146.4
(FastEthernet0/0) is resync: summary configured
Rack1R1(config-if)#
Rack1R1(config-if)#do sh ip route eigrp
155.1.0.0/16 is variably subnetted, 4 subnets, 2 masks
D 155.1.0.0/16 is a summary, 00:00:53, Null0
Rack1R1(config-if)#ip summary-address eigrp 10 155.1.0.0 255.255.0.0 255
Rack1R1(config-if)#do c
1d21h: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 10: Neighbor 155.1.146.4
(FastEthernet0/0) is resync: summary configured
Rack1R1(config-if)#do clear ip route *
Rack1R1(config-if)#do sh ip route eigrp
Rack1R1(config-if)#do sh ip route eigrp
Rack1R1(config-if)#
HTH,
Mohammed Mahmoud.
