Eigrp Routing issues

[dmoorefnlc]

Please see txt file with all the info.

Summary-

Want use EIGRP as my primary routing protocol between two sites. If connecting Layer 2 circuit betweens sites fails, floating static routes will take over and direct traffic to a vpn device.

Problems:

1.Can't get EIGRP to redistribute static routes between sites. So my floating static routes are sending traffic over the VPN not the ethernet interfaces.

2. Also getting the "Neighbor xxx not on common subnet for VlanXXX"

Thanks

I wasn't able to look closely at your config attachment. But, I see a problem with the config.

1. Your static routes aren't being redistributed into EIGRP because you are missing metric for redistributed routes. Try this 'redistribute static metric 10000 1000 255 1 1500' under EIGRP.

2. Neighbor xxx not on common subnet indicates the router is receiving an EIGRP hello packet on an interface from another device on a different subnet. Check the IP/subnet mask.

Let us know how it goes.

Pls. rate all helpful posts.

HTH,

thanks for the input. I didn't think I needed a static metric if static routes were used. thought the metric was for rip/ospf etc.

The two sites connect to each other via a 100meg layer 2 "shared" subnet on vlan192. Vlan192 will be doing "geo-clustering" for SQL and MS-exchange. So it just looks like one big Layer2 network.

Site 1=192.168.0.2 /22

Site 2=192.168.3.6/22

Site 1's default route is 192.168.3.6. it pulls all traffic from site two.

My topology shows EIGRP only on the Vlan192 on both sites. that is the only common interface that connects the two sites

Will give the metrics a try when I get in the office tomorrow.

Redistribute static did not work. My site two is not redistributing the static routes into EIGRP. Site 1 is not getting my site2 static router, so my floating statics are directing 192.168.150.x, 70,x, etc to my 10.20.2.254 gateway, not using EIGRP and going via 192.168.3.6

Still not seeing Static routes being redistributed into Eigrp on either side.

Thoughts?

[b-ulrich]

Hi, I believe it is your stub command causing the redistribution issue. Try eigrp stub connected static and see if that works.

[dmoorefnlc]

YES!!!! that was it, now my static routes are flowing
