I have 3 routers in the same LAN, say R1(10.1.1.1),R2(10.1.1.2) and R3(10.1.1.3), they are running EIGRP now, how do let r1 and r2 communication each other tp form a eigrp neighbor without send any eigrp related packet to r3?

Hi,
One thing you could do is to use the neighbor statement under the EIGRP process on R1 and R2:
R1:
router eigrp 100
neighbor 10.1.1.2
R2:
router eigrp 100
neighbor 10.1.1.1
Hope that helps - pls do rate the post if it does.

thanks for your reply. please look at my example:
R1(router)--------R2(Cat 3750 with lay3 enabled)----R3
r1:
router eigrp
network 12.12.12.0
r2:
int vlan 1
ip addr 12.12.12.2 255.255.255.0
router eigrp 10
network 12.12.12.0
neighbor 12.12.12.1 vlan 1 (define the r1 neighbor)
r3:
router eigrp 10
network 12.12.12.0
but from the r2, I show ip eigrp neighbor, not any neighbor can be seen. If I remove the "neighbor" command, I saw 2 neighbors.

by the way, are there any ways to implement this except "neighbor"?

Hi,
"if you want the outgoing routing updates alone be suppressed but the inbound updates continue to be received (and the routers still continue to be neighbors), then use the distribute-list command"

a 'distribute-list' in on R3, with sources R1/R2 denied?

it is not routing update issue, I even don't want them to form eigrp neighbor even they are runnig the same eigrp and in the same AS.

Hi, perhaps make the interface to R3 passive.

Yep, use passive interface on R3
