EIGRP neighborship on secondary address

All Cisco documents says it is not possible to create EIGRP neighborship on secondary addresses. 

Let test in our LAB and check if it really a true statement.



R1:-

interface FastEthernet0/0
 ip address 112.112.112.1 255.255.255.0 secondary
 ip address 12.12.12.1 255.255.255.0
 no shut
end

router eigrp 1
 network 112.112.112.1 0.0.0.0


R2:-

interface FastEthernet0/0
 ip address 112.112.112.2 255.255.255.0 secondary
 ip address 12.12.12.2 255.255.255.0
no shut

router eigrp 1
 network 112.112.112.2 0.0.0.0

Verification:-

R1#sh ip eigrp neighbors
EIGRP-IPv4 Neighbors for AS(1)
H   Address                 Interface       Hold Uptime   SRTT   RTO  Q  Seq
                                            (sec)         (ms)       Cnt Num
0   12.12.12.2              Fa0/0             12 00:28:42   80   480  0  7

We saw in our verification section that neighborship has come up. But how it can be possible?


Neighborship is up because of the below two conditions:-

1.        Network command enable Eigrp on the interface and it will not check whether it is of primary address or secondary. As soon as network command subnet under EIGRP process matches with any interface it start sending the hello packets using the primary address.

2.       Both the neighbors must have primary address in same subnet.

Let’s have a look at the hello packets by enabling debug on R1. 

It shows that hello packets are generated using primary address as the source IP of hello packets. It means hello packet will always use Primary address as source.


EIGRP Packet debugging is on
R1#
