Hi All,
I have a 1721 router with a WIC 4ESW 4 port switch card and an integrated T1 controller.
I have a T1 to the core of my network going into this Cisco 1721 router. I need have all the devices plugged into the 4 port switch on one network and the T1 controller on another network. These two networks converge at the 1721 router. When I plug the router in eigrp advertises the route of the serial interface that is directly connected. The problem that I am looking to solve is how can I get the network that I am using for the 4 port switch to advertise?
below is my config.

The 4 ports belong to Vlan 1 and you have an IP address under Vlan 1.
This address is already under the EIGRP process.
Are you saying the remote EIGRP neighbors aren' receiving this route?
Can you post the show ip route from this router and remote neighbors?

Edison is correct that your EIGRP should advertise the network of the VLAN. One thing that is necessary for that to happen is for the VLAN to be in an up/up state. Can you post the output of show ip interface brief to verify whether the VLAN is up?

Looks like vlan 1 is up/down
#sh ip int bri
Interface IP-Address OK? Method Status Protocol
FastEthernet0 unassigned YES NVRAM up down
FastEthernet1 unassigned YES unset up down
FastEthernet2 unassigned YES unset up down
FastEthernet3 unassigned YES unset up down
FastEthernet4 unassigned YES unset up down
Serial0 192.168.143.2 YES NVRAM up up
Vlan1 10.143.1.1 YES NVRAM up down

One of those ports (F0 - F4) needs to be up/up for Vlan 1 to be up/up.
Once Vlan 1 is up/up, it will be advertised into EIGRP.
HTH,

The vlan 1 interface comes up when I plug in a device, and the route to the 10.143.0.0 network shows up. I can now ping from the remote 10.143.0.0 network to the core but I can not ping from the core to the remote network 10.143.0.0 network. I can ping the router serial interface 192.168.143.2 from the core, but I can't ping a device on the 10.143.0.0 network. I am able to ping interface vlan 1 ip address 10.143.1.254
BTW i changed the interface vlan 1 ip address to 10.143.1.254 (it was 10.143.1.1)

If you can ping from a client in the 10.143.0.0/16 subnet to the core but you are unable to ping from the core back to the client, I suggest to make sure the client does not have any FW enabled.

FW not enable still same issue.

You could have overlapping subnets somewhere in your routing table.
Check the routing table from the Core and make sure it goes to the respective spoke.
