Dear Expert,
previously, I had 5 networks (172.16.0.0/16)
172.16.1.0/24 -> Head Office
172.16.2.0/24
172.16.3.0/24
172.16.6.0/24
172.16.8.0/24
now I have one new network on 192.168.210.0/24 connected with frame relay
when running "sh ip route" .. I did not find my 192.168.210.0 EIGRP route info .. why
please help, thanks a lot in advance

Hi Winanjaya,
The problem that you have is that you have the same subnet both at the HO and the RO. Check your config
Route 3640 at HO
interface FastEthernet0/0
ip address 192.168.210.164 255.255.255.0 secondary
ip address 172.16.1.2 255.255.255.0
Router 1700 at New Branch
interface FastEthernet0/0
ip address 192.168.210.161 255.255.255.0
speed auto
If you want 192.168.210.0/24 at Remote office then please take out the secondry ip address with subnet 192.168.210.0/24 from the Head Office 3640 router and also from the EIGRP process. I have explained in my last post the problem that you are getting into because of this configuration on HO router.
On your 1700 router at RO please include 192.168.210.0 under the router's EIGRP process.
If you have any other requirement, please explain.
HTH, Please rate if it does.

Hello,
is the interface configured with IP address 192.168.210.X/24 active on your router ?

Hi
The subnet seems to be directly connected to the router in question and hence is reported as connected in " sh ip route " output
HTH,

Narayan
The connected interface is 192.160.0.0/20 (which is a mask of 255.255.240.0) which covers the addresses of 192.168.0.0 through 192.168.15.255. The network that Winanjaya is looking for is 192.168.210.0 which is not connected according to the routing table.
The original post refers to the 192.168.210.0/24 as connected via Frame Relay, so I believe the real question is what router that is connected to and whether that router is running EIGRP and whether that router has a network statement for 192.168.210.0.
Note that there is no benefit in having a network statement for 192.168.210.0 on his router if that network is not connected to his router.

Hi All.. I am very new with this, what I don't understand is why 192.168.210.0 is not in EIGRP routing table..
could any body please help how to do this? meant how to make 192.168.210.0 in EIGRP routing table? ..
many thanks in advance

The points that I made were intended to help you solve your issue. You need to tell us what router is connected to the 192.168.210.0 network and you need to tell us whether that router is running EIGRP and advertising to your router. And you need to tell us whether that router has a network statement under router EIGRP for 192.168.210.0.
If you answer those questions you will probably have solved your own issue. And if you do not solve the issue with that information when you tell us the answers then we will be able to help you find the solution.

On your branch router (Ro_Admedika) under the router eigrp 100 configuration add the
following
network 192.168.210.0
This will then cause the branch router to advertise that network to your head office router.
Why do you have a secondary address of 192.168.210.164 on your fa0/0 interface on your head office router ??
12-08-2006 07:54 AM
Hi,
The reason you are not getting the route here on Ro_Admedika, because you have the same subnet configured here on the router's Fa0/0 interface. Since this network is directly connected so it will have an admin distance of zero and will be installed in the router's routing table rather than the EIGRP route.
There is a wrong configuration done in this scenario. You have 192.168.210.0 both at the HO and the RO. If your host sitting at RO tried to send traffic to some user at HO with destination subnet 192.168.210.x, the traffic will never pass the local router at RO as the same subnet is locally connected to the router.
You have to change the local LAN subnet ip address at Ro_Admedika RO router and then you will see the subnet 192.168.210 and everythign will work properly for you.
HTH, Please rate if it does.

I think the 192.168.210.0 is at the RO. The original post said the new 192.168.210.0 network was connected via Frame relay so i assumed this was the RO. Hence he would need to remove the secondary 192.168.210.0 address off his HO router and add a 192.168.210.0 statement to his R0 eigrp config.
Winanjaya
could you confirm where the 192.168.210.0 network is meant to be - the head office or the remote office ?
12-09-2006 09:02 AM
Yes, 192.168.210.0/24 is on remote office, at HO the network is 172.16.1.0/24, any idea?
