Getting EIGRP to work on a Cisco 2811
Posted on 2006-06-02
I have recently brought a remote office onto my network, and installed a 2811 at the new site.
S0/0/0 - T1 DSU that terminates a T1/frame-relay connection to the corporate head-end ATM bundle.
FA0/0 - to the office's existing DSL connectivity by way of a PIX 506e. The PIX is 172.16.0.1/30, FA0/0 is .1 with a slash 30, this interface's IP is 172.16.0.2/30.
FA0/1 - 192.168.0.1/25, and attaches to a Cisco 2950 switch. This is the default gateway for everyone now and their LAN IP's are on the 192.168.0.0/25 subnet.
As far as routing - I need any requests for 192.168.1.x, 192.168.2.x, and 192.168.3.x (all are /24) to go out the Serial interface to our corporate network. Anything else (i.e. default route) is static'd to go to the next hop of 172.16.0.1 (PIX) and on out to the Internet.
The 192.168.1, 2, & 3 networks I would have expected to be learned via EIGRP just like all the other branch offices, but I was not getting any EIGRP routes across the frame-relay at all. If I do a 'sh ip eigrp nei' on the 2811, I see no neighbors, and I should be seeing the corporate head-end router. There is nothing stopping EIGRP at the head-end. Is there a line in the 2811 config that is new and needs to be there to get EIGRP up and running to not only learn routes, but send the route for 192.168.0.0 back to the head-end at corporate? For now I just have them static routed which is ok, but doesn't follow the usual model.
Also, and maybe related - I can't get traffic from FA0/1 to route and go out on FA0/0. As you already know, any traffic not destined for a corporate 192.168 network, I want to default route to the PIX and on out to the Internet. I need traffic from the workstations, hanging off of FA0/1 to default route to the PIX attached to FA0/0. My default route is:
ip route 0.0.0.0 0.0.0.0 172.16.0.1
From the router, I can ping external addresses just fine. From the switches or workstations, I cannot. Any ideas what I am missing?
Thanks in advance.
