you are right, if you look at other location config in that i am summerz the routes(10.70.0.0/16) on interface sending to other site ryt.. In that my interface IP(10.255.10.70) is not comes under that range.. how come EIGRP got established to other location..
interface GigabitEthernet3/0/14 no switchport ip address 10.255.10.70 255.255.255.0 ip summary-address eigrp 100 10.70.0.0 255.255.0.0 5 speed 100 no mdix auto
router eigrp 100 passive-interface default no passive-interface GigabitEthernet3/0/14 network 10.0.0.0 no auto-summary no eigrp log-neighbor-changes
One more when I check the routes at other end(Neighbor location) for the location which has enabled for autosummary by default...showing classless routes..its suppose to show classfull right as i have enanbled auto on EIGRP(default behaviour)..
Neibhor location# sh ip route | i 10.53 D 10.53.30.0/24 [90/28416] via 10.255.10.53, 06:57:07, GigabitEthernet3/0/14 D 10.53.20.0/24 [90/28416] via 10.255.10.53, 06:57:07, GigabitEthernet3/0/14 D 10.53.10.0/24 [90/28416] via 10.255.10.53, 06:57:07, GigabitEthernet3/0/14 D 10.53.4.0/24 [90/28416] via 10.255.10.53, 06:57:07, GigabitEthernet3/0/14 D 10.53.99.0/24 [90/28416] via 10.255.10.53, 06:57:07, GigabitEthernet3/0/14 D 10.53.200.0/22 [90/28416] via 10.255.10.53, 06:57:07, GigabitEthernet3/0/14
The problem is not with the summarization. The problem is with how you changed the selection of interfaces participating in EIGRP.
First let us review a fundamental aspect of how EIGRP works. The main function of the network statement in EIGRP is to identify the interfaces on which EIGRP will process. The router (or layer 3 switch) running EIGRP looks at all of the configured network statements and looks at all of the interfaces and finds interfaces that match one or more of the network statements. EIGRP will process on these (and only these) interfaces.
So when your configuration included the statement network 10.0.0.0 then any interface in network 10 (including 10.255.10.53) were active EIGRP interfaces and formed neighbor relationships. When you removed the network 10.0.0.0 statement then the only network statement was network 10.53.0.0 0.0.255.255 and only interfaces that match 10.53 were active EIGRP interfaces. Since 10.255.10.53 no longer matched a network statement it stopped being an active EIGRP interface and the neighbor relationship went away.
You asked about the impact of adding log neighbor and the answer is that it would have very minimal impact on router performance.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
